Rational number - (ANSWERS)A number that can be written as a ratio of integers, which means
!@#$%%%%%
it can be written as a fraction. %%%%%%
Product - (ANSWERS)The result of multiplying values.
Whole number - (ANSWERS)A number whose value is 0 or greater and can be represented
without a fractional or a decimal component.
Identity property - (ANSWERS)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 - (ANSWERS)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 - (ANSWERS)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 - (ANSWERS)In mathematics: a collection of numbers.
Order of operations - (ANSWERS)A set of rules that defines the order in which mathematical
operations should be performed
Multiplicative inverse - (ANSWERS)The number you must multiply x by to get 1. For example, 5
and 1/5.
Principal square root - (ANSWERS)The positive square root of a number.
Interval - (ANSWERS)A set of numbers between two specified values.
Operators - (ANSWERS)A word or symbol (such as + or -) that indicates an operation between
values.
Commutative - (ANSWERS)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 - (ANSWERS)The symbol which indicates to take the square root of the number
%%%%%%
that follows.
Additive inverse - (ANSWERS)Two numbers equidistant from 0 on a number line whose sum is
0. For example, 3 and -3.
Greatest common factor (GCF) - (ANSWERS)The greatest number that is both a factor of a and
a factor of b.
Factor tree - (ANSWERS)A graphical method used to identify the prime factorization of an
integer.
Integer - (ANSWERS)A number, (positive, negative, or zero), that can be represented without a
fractional or a decimal component.
Discrete - (ANSWERS)A collection of numbers whose values are distinct, separate, and
unconnected.
Prime factorization - (ANSWERS)Determining the set of prime numbers whose product is the
original integer.
Continuous - (ANSWERS)A collection of numbers whose values are not dividable into distinct
units.
Expressions - (ANSWERS)A string of terms that are connected by division, addition, and
subtraction operations.
Quotient - (ANSWERS)The result of a division expression.
Exponents - (ANSWERS)Sometimes called a power, it is a quantity that represents repeated
multiplication.
Factor - (ANSWERS)An integer that divides another integer. We say an integer, x, is a factor of
another integer, y, if the quotient y/x is also equal to an integer.
Composite number - (ANSWERS)A number with more factors than just one and itself. Not a
prime number.
