Integers are numbers which can be represented without decimals, they can be negative or positve.
1. The delivery fee is 4.99 which can be rounded up to 5. The integer would be 5.
2. 17 feet above the surface. The integer would be 17.
3. Is -3 less or greater than -8.
For negative numbers the closer they are to "0" the greater they are, therefore -3 is greater than -8. -3 > -8
