Homework Time Math Puzzle
Call me a nerd (hey, I do write for Mental_floss), but I kind of miss my math homework. Back in the days before algebra and trig, math homework meant math problems embedded in intricate stories, arithmetic trickery and the occasional logic puzzle. In short, they were the kinds of puzzles that people secretly love to do in their free time. But once high school hit, math problems got a lot more tedious and complex and less fun. Now that I'm in college, I've completely ditched math and if it weren't for my obsession with sudoku and kakuro, I doubt I'd use my left brain at all.
So, for the sake of geeky nostalgia, here's the kind of homework I wish I could still get from math classes. Be sure to chime in with the problems you couldn't wait to get home to do.
Hanging Balance Problems
Different shapes hang in balance in elaborate, mobile-like structures. With just a few clues, it was up to you to figure how much each shape weighed in order to keep everything in balance. Looking back, those balance problems were just a sneaky way to get 5th graders thinking about algebra, but making equations with triangles and cubes is way more appealing than thinking in terms of x's and y's. These were by far my favorite form of math homework- I would even ask for extra problems and often my parents would even make their own copies to make math homework a family affair.
Crossfigures
I like crosswords. I like math (to a point). So the crossfigure seemed to be the best of both worlds. The crossfigure is just a crossword puzzle, only with numbers. The clues often played off each other (like "29-across minus four"), so solving them involved some knowhow. I didn't get them as homework so often, mostly just as a fun break from the daily grind.
Bobo's Word Problems
Sadly, I can't give you many details on this- Bobo was a character in a series of word problems I was given for a class. Something about having a recurring character (especially one that I imagined to be a clown) just made word problems a little easier to swallow. In fact, I liked the Bobo problems so much, my sixth grade math fair project was just a series of Bobo's adventures that I solved.
Anything related to sports
Even though calculus had it's fair share of word problems, they just weren't real enough situations. When will I be trying to figure out the volume of a tank of oil that is simultaneously being filled and drained at different rates? Even the old-school arithmetic problems were a little hard to grasp- who shares apples anyways? But sports made word problems easier to handle. Figuring out different ways to make an NFL team score 20 points or figuring out a pitcher's ERA made math fun. Thankfully, fellow blogger Sandy was able to bring back that feeling with this Brain Game last month.
miscmath
google, the internet's largest search engine, has added more functionality to its already popular offerings. the website has given its search service the ability to perform mathematical calculations–simply typing a formula into the search box will return the answer. additionally, the formula can be formatted in several different ways, such as 35*10, thirty five * ten, or even thrity five times ten.
but the calculator goes beyond simple multiplication and subtraction. within its functionality is the ability to perform conversions, such as meters to a mile or teaspoons in a cup. finally, as suggested by google's calculator description, the search engine “can evaluate mathematical expressions involving basic arithmetic (5+2*2 or 2^20), more complicated math (sine(30 degrees) or e^(i pi)+1).”

christopher's opinion
too bad google can't also make a “way-back machine” so i can retake some of my early algebra classes. man, do kids nowadays have it easy! i remember being excited when solar calculators came onto the market.
google just keeps adding to its functionality, which is why it remains the number one search engine. as others such as yahoo! and askjeeves try to keep pace, google continues to raise the bar. i still use both yahoo! and google, but more and more i rely on the latter.
sure, the calculator is a little gimmicky. how many times does a person really need to know anything to do with math, gigawatts, miles per hour, and newtons? but it will be a nice little resource the next time i get confused trying to remember how many fluid ounces in a cup or pecks in bushel.
is it the greatest thing ever? not even close, but it makes google that much stronger.

google*mart(9:32am est tue aug 19 2003) next…google allows you to search wal*mart with your cell phone to find out exactly where the lightbulbs are. – by m@ |
you'd be surprised christopher!(9:41am est tue aug 19 2003) “how many times does a person really need to know anything to do with math, gigawatts, miles per hour, and newtons?” there are lots of people who have to deal with this daily. i am one of them. i use google all the time for research, so why not use it for calculating complex formulas for something such as fiber optics! – by scientist |
really?(9:42am est tue aug 19 2003) “or even thrity five times ten.” so it fixes the typo, then gives you the correct result? astounding. – by simon |
you know,(9:45am est tue aug 19 2003) this sounds great, but as a software developer dealing with vector graphics, when i need to find out about some algebra formulae, or other 3d equations, the internet is almost always the last place i look. it's not that you can't find answers to your math problems online, it is just that you have to wade through countless web sites dedicated to teaching you how to solve the problems, rather then solutions to those problems. searching for a solution to an algebra problem, i had to skip 7 full screens of google results to find a site that actually had the formula i was looking for, the previous seven pages of results were from high schools and universities that offered test and quiz questions (without answers by the way), and student pages about the proof of the formula, not on how to solve it. i can understand that students need to learn how to solve these problems, not just handed the solution, but i already paid my dues and went to school. so, when i want answers, i want anwsers, period. hopefully, more sites like this will be dedicated to answering math problems, rather then attempting to teach you. i allready lernd all i want, and i ain't interested in lernin' any more. i gets paid for providing solushuns, not lernin'. – by topher |
not science(9:48am est tue aug 19 2003) i think this is a great idea, except what good does it do me to know that one hundred million times one hundred million = 1.0 � 10^16 ?? i want the full spelled out number! so i have this strange fascination with numbers, so what? – by 10011010 |

i have been (10:00am est tue aug 19 2003) trying to teach my 9 year old granddaughter to do simple math in her head. it seems to me that folks are intent on 'dumbing down' everything as much as possible. if your power is down, ( what? no electricity??) and you cannot do math in your head, or with pencil and paper, ( i'll confess, i can not do quadratics in my head.(( i guess i'm gettin old too, topher))maybe you should apply for a job at the saw mill. – by darwin |
topher(10:05am est tue aug 19 2003) you sound like a good guy, but we both read the latest tech news. if we are not prepared to learn whatever new gizmo which is going to be headlined in next monday's “geek.com” maybe we both can get a job at ” thet ol' (patoie) sawr mill. saw if you are from the northeast, sawr, if you are from the north west. :) – by darwin |

yuhoo(10:35am est tue aug 19 2003) precise inside my search engine, it continues the fact that it increases the function to remain to peel why, google? yahoo which it sees on top outside, it will seem the width of maintenance of reading askjeeves' large foot made walk of google, an area of method it will reach and holds. i however the afterwords of yahoo hemm and the positive one but, depends google two, were in top significant, it employed. – by dominiqu3 |

calculators(12:35pm est tue aug 19 2003) calculators and formula 'cheat sheets' don't dumb you down they rid you of the trivial tasks and allow you to focus on larger problems. who cares if you have to look something up. as long as you know what you're looking for and more importantly how to apply it, all is golden. in the real world, the one that depends on electricity, there are plenty of calculators. they make us smarter. this entire argument that we would be lost/ignorant/helpless without technology is so old. without technology there is no way we could feed 6 billion people. without calculators we won't be able to feed 10 billion. get used to it. there's no going back. – by lb1 |
ppl are getting stupider(1:12pm est tue aug 19 2003) ppl are just gettin stupider by the day we don't need tools for brats we need better teachers – by m0r0m0n |
dumbing down?(1:20pm est tue aug 19 2003) calculators don't dumb us down, hell i was taking college math classes that required state of the art $200 dollar calculators just to take the class. they help speed up our knowledge and apply the steps for us, imagine you're on a space flight, re-entering the atmosphere and a problem arises. “sir, we're losing our vector due to wind velocity, let me punch it in to the computer and have it calculate a course correction!”. “well, sorry bob, the computers calculation functions were removed due to the fact it dumbs us up, give me a couple hours and i'll figure out the correction on paper!” – by crevin |
dumb versus unreasonable(2:03pm est tue aug 19 2003) the problem with *only* doing math on a calculator or computer is that you don't get a “feel” for numbers. when the kids today accidently punch in 100 * 2, instead of 1.00 * 2, they don't even notice that 200 is an *unreasonable* answer for two times one. that's the real problem. – by dung |
blind reliance(2:08pm est tue aug 19 2003) i think what darwin was referring to was blind reliance on technology. yes, your $200 calculator can save you a lot of time by performing simple steps for you, but if you don't understand the underlying concept, you haven't learned how to do the calculation. you've simply learned to punch numbers into a formula. i knew way too many people in college who treated math as a black box (numbers in – answer out), and it ended up biting them in the a$$ come test time. my freshman chem professor taught us to do logs in our heads so that we would have an idea if the number our calculator gave us was in the ballpark. if you were one of those people who understood the concept and used the technology to further that knowledge, then good for you. you have mastered a very powerful tool. – by laserman |
calculator vs computer???(2:56pm est tue aug 19 2003) it doesn't take google's calculator to dumb down america. it's already being done quite well by our television programing and other aspects of our society. in addition, it's often not the teachers, but rather the apathetic lazy attitude of people that believe they deserve everything while doing the least possible amount of work/effort. pardon the digression. my thoughts on google is that windows operating systems (and other systems)already have a calculator program that does complex math. so if someone wants to take the extra time to go to google and type out equations in long format, that's their perogative. as for something that does mathamatical conversions, i found a simple free non-invasive program called “convert” that is much easier to use than google will ever be. such programs are easily found at in the end, those people who do complex math are more prone to already have a scientific calculator to assist them. scientific calculators are more conveinent and are also cheaper than the monthly internet cost to use google for math. if you don't know how to use a calculator, you ought to have spent more time listening to the teachers while you were in school. life doesn't need to be further compartmentalized. – by meson |
a little too late(3:01pm est tue aug 19 2003) why couldn't this be done while i was taking all of those physics classes? – by esqin |
no calculator, no problem(3:07pm est tue aug 19 2003) i seemed to make it through college fine without a $200 calculator and i got a degree in math. the classes that required the graphing calculators were the 1000 level classes for business and non-technical majors. i did depend on math world at wolfram research (mentioned by math man). i would have to say that i am impressed with the calculator from google, not because of its calculation ability, but because it is “smart.” i thought that i could give it a problem it couldn't solve. i asked it for “100 calories in calories” and it recognized the difference in capitalization giving me the answer “100 calories = 0.1 kilocalorie.” – by another math man |
no boobs, no problem(3:30pm est tue aug 19 2003) boobs are just gettin larger by the day – by hugh jeboobs |
re: hugh(3:33pm est tue aug 19 2003) are you suggesting that those that use calculators are boobs? or that those that don't are boobs? – by tina tits |
when(3:53pm est tue aug 19 2003) i was in college back in 1964, a physics prof told me that my not knowing how to use a slide rule should get me removed from his class. i sat down and learned how to use one. my objection is not that someone uses a tool to save time, but mis-using the tool because one is too lazy to try to learn how. lets face it, i cannot do matching orbital velocity vectors in my head, *or* on paper. but, i save a few bucks a year because i can do sales tax in my head, close to a couple of pennies. the kid who is punching items on the registers touch pad has no idea if the total is right or not. and most of them don't care! – by darwin |

so how(6:34pm est tue aug 19 2003) do i enter an inverse tan into google? oh, and calculators are more efficient. sure i can calculate the sin(33.2) on paper but why would i want to when i have a calc? – by duh |
adnumbers(11:58pm est tue aug 19 2003) and now in addition to the popular “adwords” program where advertisers buy ads associated with keywords, this opens up an infinite supply of “adnumbers” to be sponsored. – by einstein |
great(1:00am est wed aug 20 2003) now, not only can we steal music, we can cheat on our math homework – by great |
m0r0m0n(1:17am est wed aug 20 2003) as i teacher, i'm offended by your comment. the greatest teacher in the world can't teach children who aren't willing to learn. and children who aren't willing to learn get that way by having parents who aren't willing to reinforce the importance of having a good education. these are the same parents who use video games, the computer, and tv as a babysitter. look at how little teachers are paid, and you'll understand the value us society places on formal education. those who go into teaching often do so because they're good at it, dedicated to helping, and don't mind living from paycheck to paycheck. if you want better teachers, learn to be more hands-on parents and don't gripe when your community increases taxes to give teachers raises and attract talented people into education. otherwise, you're perpetuating the problem. – by sam |
like kids don't have calculators(1:48am est wed aug 20 2003) why the heck does google think kids would rather wait two minutes for their computer to boot up, another 2 minutes to dial up the internet and then type in their math problems. kids have 99 cent freakin calculators in their backpacks that can do it all for the them. i can understand a complete idiot like al gore (board of directors) promoting this, but come on my fellow geekians. – by thegoodgeek |
here we go again…(10:08am est wed aug 20 2003) god, if i hear another teacher complain about how tough they have got it. 1) they only work about eight months a year with vacations and days off. 2) they get better benifits than 90% of the rest of us working stiffs. 3) most teachers only teach a couple a classes a day. 4) in cleveland where i live, the average salary for a teacher is over $33,000/year with a ba and over $60,000/year with a ma. not too shabby when you take everything into account. – by bah! |
re: bah!(6:39am est thu aug 21 2003) ok, i'd like to see you try teaching anything to a room full of 14 yr olds. since you seem so knowledgeable about how things should be, why don't you jog on over to your nearest high school, and volunteer to help out for a day or two. i doubt you'd hold the same perspective after an experience in a real learning environment. stupid git. – by sliver7 |
