What’s a whole number?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.*
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.
