Math Homework Cheating Machine

Does math and shows its work
  (+17, -2)(+17, -2)
(+17, -2)
  [vote for,

The math homework cheating machine does addition, subtraction, multiplication and long division. Unlike a calculator it shows its work, complete with little numbers written above other numbers and some numbers crossed out to indicate carrying and borrowing, not to mention place-holding zeroes. It then renders the work in realistic handwriting and prints it in the same shade of gray as an HB pencil (erasable ink) on wide-rule three-hole-punched loose-leaf paper. And it writes your name in the upper-right-hand corner.

All you have to do is type in the math problems. Your teacher will never know.

Not a cheater, but a sudy tool http://math911.com/

This calculator will simplify your equations for you. [zen_tom, Feb 04 2010]

Pretty cool really. [zen_tom, Feb 04 2010]


       You're only cheating yourself. (smiles knowingly at the reference to HB pencils)

       It should make mistakes occasionally, or your teacher will definitely know.

       Thinking more about the idea, I think it may actually be a useful learning tool. If you're not sure how to solve a problem, you no longer have to wait to ask a teacher. I think I'd use it, even though I'm a professional engineer. Of course it would need to solve integrals.
Worldgineer, Feb 20 2004

       Can I bring it in at test time?   

       Actually, this is too late for me. I already passed my math classes the hard way, dammit. Where were you for those first two calc classes I had to drop?

       I was behind you in line at the registrar’s office.
AO, Feb 20 2004

       Oh. You look taller on the 'bakery...
k_sra, Feb 20 2004

       So Worldgineer's an engineer...

       Math 911[link] grills the student on canned math problems, and will explain the solution, step-by-step if the student runs in to trouble.   

       [AO] Parents could use your invention to help their offspring with homework [+]

       Just to point out that it would need costomizability; I wright my carrying numbers where they go, and then wright over them:

       986 >> 986 >> 986 >> _986 341 >> 341 >> 341 >> _341 000 >> 007 >> 127 >> 1327

       I think that kids try to take too many short cuts the way it is. It is best we take the time and just learn it. If we do not then our kids will grow up without ever learning how to do something simple like balancing a checkbook. Anyway there are some math tools out there that already do this. I experimented with them in some advanced Calculus classes.

       True - I refused to use a calculator in school & always read ahead one chapter - result: got highest Math Aptitude Tests/SAT in county, though I only took Algebra & Geometry & couldn't be bothered to arrive on time, if at all - to actual Math classes. (Generally, I'd show up to school at 10:00-10:15, just in time for the break) 1st Teachers on my schedule hated my guts.

       where can i get this machine? i think it would even be very helpfull
leashonafreak101, Mar 11 2005

       i need to cheat
jordan1234, Apr 06 2006

       How the f**k do i start cheating????!!!!
jordan1234, Apr 06 2006

       Beware of angry people.   

       [jordan1234] This doesn't exist yet, it's just an idea.
DesertFox, Apr 06 2006

       Attempted sign-ups for the website that implements this since jordan1234: 24 [last: Apr 17 2011]   

       [This may appear like a low number, but it must be a small percentage compared to the frustrated visitors who at some point figure out that this is a suggestion rather than an invitation.]
jutta, Jan 31 2007

       I've never seen this idea before - I need this machine.   

       [AO]: Where can I get one? Can it do differential equations? Integration by parts? Guassian elimination (I **always** make a stupid mistake when doing that) ?
Jinbish, Jan 31 2007

       Actually, i think this is highly plausible.   

       Maybe a scanner with some OCR software and a DIY CNC machine with instead of a blade it has a pencil or pen attached. I think the hardest part would be the programming, but i imagine highly doable!   

       Could sell the machines for like $200 a pop!   

bbglas007, Feb 04 2010

       Heard of Wolfram Alpha (well, since 2009)? You could easily use it and copy down its math problem steps with a little erasing for good measure.
paix120, Feb 04 2010

       I'm doing a thing at the moment that involves maths homework, it's actually very theraputic, like crosswords, soduku or the like. I bet if newspapers printed lists of bracketed equations to express in simple terms, there'd be people on trains and busses who'd lap it up!
zen_tom, Feb 04 2010

       Not a bad idea really. Although it should stop short of calculus.
wagster, Feb 04 2010

       [+] Brilliant. I did not write this annotation, I used my annotation cheat machine.
S-note, Feb 04 2010

       Stop short of calculus? Then how the hell am I meant to do 2nd order differential equations? Laplace transforms? Fast Fourier Transorms? Finite Field Theory?   

       At this rate, I may as well go learn them myself.
