, rational number A number that can be written as a ratio of
integers, which means it can be written as a
fraction.
product The result of multiplying values.
whole number A number whose value is 0 or greater and can be
represented without a fractional or a decimal
component.
identity property The property that 0 can be added to any number
without changing the value of the number.
Likewise, 1 can be multiplied by any number
without changing the value of that number.
associative property The property that under certain operations in a
multi-step expression, the computations may be
done in any order. Commonly represented as (a +
b) + c = a + (b + c). Addition and multiplication
both have this property, but subtraction and
division do not.
perfect square The product of any integer with itself yields this.
So, a number is this if it can be written as the
square of an integer. For example, 9 is this
because 3 * 3 = 9. Other examples are 16, 25, 36,
49,...
