 Jul12 comment What exactly is a number? Oh, I see, but they would have to be over a a field that already satisfied those characteristics. Jul12 comment What exactly is a number? I never mention matrices in my answer though, well yes, if you don't consider quaternions or octonions you can include associativety and commutativity as characteristics, I thought quaternions were considered numbers, because I have heard of people talk about the quaterions as a number system.

I don't know, but they're usefull Jul12 awarded Favorite Question Jul12 awarded Nice Answer Jul11 comment How to find know if function is onto? if you take a function with finite domain then the fibers of the image of the functions will form a partition of the domain, so the image of any function with finite domain has cardinality less than or equal to the domain. So if the codomain is larger than the finite domain, we can be sure the map is not onto. Jul11 comment How to find know if function is onto? @Teepeemm really? could you provide an example? Jul11 comment Discrete math and recursion problem. fixed, thank you. Jul11 answered Discrete math and recursion problem. Jul11 comment How to find know if function is onto? No what I am saying is if $x$ leaves residue 1 when divided by $3$ then $2x$ leaves residue $2$ when divided by $6$, if $x$ leaves residue $2$ when divided by $3$ then $2x$ leaves residue $4$ when divided by $6$, and if $x$ is a multiple of $3$ then $2x$ is a multiple of $6$.
