Whole Numbers
whole number
a counting number or zero
repeating decimal
a decimal that does not have a definite end to it (The place value of the last digit in the number cannot be found.)
terminating decimal
a decimal that has a definite end to it (The place value of the last digit in the number can be found.)
rational number
a number that can be written as a ratio of integers
irrational number
a number that cannot be written as a ratio of integers
real number
a number that is rational or irrational
perfect square
a number that result from multiplying an integer by itself
square root
a number that when multiplied to itself results in a specified number. The square root of 25 is 5, since 5x5=25 (25 is the specified number)
natural number
a number we count with
integer
a whole number or the opposite of a whole number
Integers
