rational number .......Answer.........A number that can be written as
a ratio of integers, which means it can be written as a fraction.
product .......Answer.........The result of multiplying values.
whole number .......Answer.........A number whose value is 0 or
greater and can be represented without a fractional or a
decimal component.
identity property .......Answer.........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 .......Answer.........The property that under
certain operations in a multi-step expression, the computations
,age 2 of 83
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 .......Answer.........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,...
set .......Answer.........In mathematics: a collection of numbers.
order of operations .......Answer.........A set of rules that defines
the order in which mathematical operations should be performed
multiplicative inverse .......Answer.........The number you must
multiply x by to get 1. For example, 5 and 1/5.
,age 3 of 83
principal square root .......Answer.........The positive square root of
a number.
interval .......Answer.........A set of numbers between two specified
values.
operators .......Answer.........A word or symbol (such as + or -) that
indicates an operation between values.
commutative .......Answer.........The property that the order of the
numbers under the operation does not change the result.
Addition and multiplication have this property: a + b = b + a
and ab = ba.
radical sign .......Answer.........The symbol which indicates to take
the square root of the number that follows.

X- Axis .......Answer.........The horizontal line that passes through
m. m. m. m. m. m.
