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 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.
,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.
additive inverse (answer)Two numbers equidistant from 0 on a number line whose sum is 0. For
example, 3 and -3.
greatest common factor (GCF) (answer)The greatest number that is both a factor of a and a factor of b.
factor tree (answer)A graphical method used to identify the prime factorization of an integer.
integer (answer)A number, (positive, negative, or zero), that can be represented without a fractional or
a decimal component.
discrete (answer)A collection of numbers whose values are distinct, separate, and unconnected.
prime factorization (answer)Determining the set of prime numbers whose product is the original
integer.
continuous (answer)A collection of numbers whose values are not dividable into distinct units.
, expressions (answer)A string of terms that are connected by division, addition, and subtraction
operations.
quotient (answer)The result of a division expression.
exponents (answer)Sometimes called a power, it is a quantity that represents repeated multiplication.
factor (answer)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 (answer)A number with more factors than just one and itself. Not a prime number.
Fundamental Theorem of Arithmetic (answer)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 (answer)A number with only two factors: one and itself.
percent proportion (answer)Proportion that is equivalent to the given ratio but has a denominator of
100.
denominator (answer)The number written after the slash, or below the fraction bar, in a fraction.
conditional proportion (answer)A proportion where one part of a proportion is a variable, or unknown
quantity.
numerator (answer)The number that is written before the slash, or above the fraction bar, in a fraction.
