Shouldn't this be a math teaser?
my pony wants to know what a vector is. please answer her question because she is in misery bc she cant figure out what vector means. please help.
AXTON ... I like this teaser ... Very nice
Pony, a vector is a length, like 3 inches. In this case, he is using a 3 inch pencil, a 4 inch pencil, and a 5 inch pencil to make a triangle.
Good teaser, but shouldn't it be under maths?
Nice one with good logic
it is just the pythagorean theorem why is it rated 3.12, its simple
Wow! I actually guessed it right keep 'em coming!
This is stupid... yes the answer makes sense but the last time I checked I'm not psychic... clearly anyone would think that you're talking about just 3 and 4 and not the directions. This shouldnt even be "logic" cuz there is no way to logically work that out. This should be at best a "trick" teaser. This is almost as stupid as saying how can 1 = 1000? because 1 kg = 1000 grams. That is STUPID
It takes a bit of logic to think of the connection from one set of numbers to another set of numbers without any background information. It could belong elsewhere, but it seems fine as is.
Pythagorean triples. Fun.
