rational number - ANS A number that can be written as a ratio of integers, which means it can
be written as a fraction.
product - ANS The result of multiplying values.
whole number - ANS A number whose value is 0 or greater and can be represented without a
fractional or a decimal component.
identity property - ANS 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 - ANS 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 - ANS 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 - ANS In mathematics: a collection of numbers.
order of operations - ANS A set of rules that defines the order in which mathematical operations
should be performed
multiplicative inverse - ANS The number you must multiply x by to get 1. For example, 5 and
1/5.
principal square root - ANS The positive square root of a number.
interval - ANS A set of numbers between two specified values.
operators - ANS A word or symbol (such as + or -) that indicates an operation between values.
commutative - ANS 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 - ANS The symbol which indicates to take the square root of the number that
follows.
, additive inverse - ANS Two numbers equidistant from 0 on a number line whose sum is 0. For
example, 3 and -3.
greatest common factor (GCF) - ANS The greatest number that is both a factor of a and a
factor of b.
factor tree - ANS A graphical method used to identify the prime factorization of an integer.
integer - ANS A number, (positive, negative, or zero), that can be represented without a
fractional or a decimal component.
discrete - ANS A collection of numbers whose values are distinct, separate, and unconnected.
prime factorization - ANS Determining the set of prime numbers whose product is the original
integer.
continuous - ANS A collection of numbers whose values are not divisible into distinct units.
expressions - ANS A string of terms that are connected by division, addition, and subtraction
operations.
quotient - ANS The result of a division expression.
exponents - ANS Sometimes called a power, it is a quantity that represents repeated
multiplication.
factor - ANS 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 - ANS A number with more factors than just one and itself. Not a prime
number.
Fundamental Theorem of Arithmetic - ANS A concept which states that any integer greater than
1 is either prime or is the product of a unique set of prime numbers.
prime number - ANS A number with only two factors: one and itself.
percent proportion - ANS Proportion that is equivalent to the given ratio but has a denominator
of 100.
denominator - ANS The number written after the slash, or below the fraction bar, in a fraction.
conditional proportion - ANS A proportion where one part of a proportion is a variable, or
unknown quantity.
rational number - ANS A number that can be written as a ratio of integers, which means it can
be written as a fraction.
