Integers
✓ ~~~ whole numbers and their opposites. Not fractions decimals and mixed numbers.
Prime numbers are
✓ ~~~ Any whole number greater than 1 that has only two factors, itself and 1; that is,
a number that can divide evenly only by 1 and itself. No remainders.
Prime numbers are
✓ ~~~ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29
Prime numbers are
✓ ~~~ 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79,

Rational number
✓ ~~~ Includes all integers, decimals, and fractions. Any terminating or repeating
decimal number is a rational number.
irrational numbers
✓ ~~~ Cannot be written as fractions or decimals because the number of decimal
places infinite and there is no recurring pattern of digits within the number. For
example pi begins with
