arithmetic refresher

Some notes on integers that I learnt today.

Integers are numbers you count with (hence fractions and roots cannot be integers)
Even integer - divisible by 2
Odd integer - not divisible by 2
prime - divisible by 1 and itself (1, 3, 5). They have to be greater than 1.
./ #star 2 is the only even prime number
0 - is the only non negative, non positive integer
./ #star Non integer value cannot be determined as odd or even

are positive integers that make up a number evenly. (finite)

integer divisible by another integer (infinite)

Left over after dividing two numbers. Will always be smaller than the number being divided by.
