For instance, the definition of Divides, Divisor, Multiple is as follows.
A nonzero integer m divides an integer n provided that there is an integer q such that n=m⋅q. We also say that m is a divisor of n, m is a factor of n, and n is a multiple of m. The integer 0 is not a divisor of any integer. If a and b are integers and a≠0, we frequently use the notation a|b as a shorthand for “a divides b.”
I've just started learning proofing techniques, and along the way the reading material I use occasionally throws a definition my way that is helpful for a certain proof. I was wondering if there is sort of a centralized database, or glossary, of these definitions that I can refer to when trying my hand at proofs -- so I can use them as reference.
Any ideas? Thank you.
