What is a whole number (and what isn’t?) Whole numbers give us an amount of whole things – not parts (fractions), and not negative amounts. Zero is a whole number (because we could have zero whole things). 0, 5, 17, 443 and 19,098 are all whole numbers. -3, 4 ½, 0.3 and 5.102 are *not.*

4
What are integers? All the whole numbers are integers… and so are negative numbers, *if* they don’t have fractions or decimals. -3 is an integer. 445 is an integer. 3.4 is not an integer; -4 ½ is not an integer. So – integers can be positive or negative or zero, but they can’t have the “in between” numbers that fractions and decimals stand for.
