So there's a couple different sets of numbers.
00:02
There's a couple differences.
00:03
So suppose i have zero, one, two, three, so on and so forth.
00:07
And then i have one, two, three, four, so on and so forth.
00:11
And then i have negative two, negative one, zero, one, two, and they extend forever on both sides.
00:17
So these are three different groups of values.
00:21
They're all real numbers, but specifically negative and positive whole numbers.
00:26
These are called the set of integers.
00:28
So integers are negative and positive whole numbers.
00:31
Inside of integers, i have something with zero and something without zero...
