[Very Hard Math Problem] How you multiply two numbers??

[OulOat]

By only using circles, right triangles, and lines? HA, tricked ya. More specifically, how can you find the product, say 2 and 3, by using ONLY geometry. No, this is not a HW problem (since I already know the answer). It would be one hell of a HW problem anyways. We take this stuff for granted, but our ancestors had to do it the hard way. I would just like to see how many ATOTers can figure this out . You would get mad props for googling it, since I couldn't find the answer on it.

*Hint - Unit circles is a good place to start.

 

[EyeMWing]

I don't.

I'm not sure if I understand but...

Couldn't you just take a square.. 2 units by 3 units

Count how many 1 unit by 1 unit squares would fit inside it..

There's your answer.

you can have 6 rocks

put em into 3 groups of 2

count all 6

and BAM you have your answer

Yeah, I don't get it. At some point you're still going to have to count something, so why would you use shapes and stuff to figue it out, especially if you have fingers

 

[dethman]

your definition of what we can use (geometry) is vague. that could mean anything.

such as the second poster...take a chunk of two 1x1 squares, and then count three of those. total number of 1x1's is your answer. after all, squares and rectangles are 'geometry.'

Using circles 2x3

OO
OO
OO

now count the circles.

lines 2X3

l l
l l
l l

now count the lines.

Same goes with Triangles or any other shape
