A number that can be written as a ratio of integers, which means it can be written
as a fraction. - ANSWER-rational number
The result of multiplying values. - ANSWER-product
A number whose value is 0 or greater and can be represented without a fractional
or a decimal component. - ANSWER-whole number
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. - ANSWER-identity 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. - ANSWER-associative property
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,... - ANSWER-perfect square
In mathematics: a collection of numbers. - ANSWER-set
A set of rules that defines the order in which mathematical operations should be
performed - ANSWER-order of operations
The number you must multiply x by to get 1. For example, 5 and 1/5. - ANSWER-
multiplicative inverse
The positive square root of a number. - ANSWER-principal square root
A set of numbers between two specified values. - ANSWER-interval
A word or symbol (such as + or -) that indicates an operation between values. -
ANSWER-operators
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. - ANSWER-commutative
, The symbol which indicates to take the square root of the number that follows. -
ANSWER-radical sign
Two numbers equidistant from 0 on a number line whose sum is 0. For example, 3
and -3. - ANSWER-additive inverse
The greatest number that is both a factor of a and a factor of b. - ANSWER-
greatest common factor (GCF)
A graphical method used to identify the prime factorization of an integer. -
ANSWER-factor tree
A number, (positive, negative, or zero), that can be represented without a
fractional or a decimal component. - ANSWER-integer
A collection of numbers whose values are distinct, separate, and unconnected. -
ANSWER-discrete
Determining the set of prime numbers whose product is the original integer. -
ANSWER-prime factorization
A collection of numbers whose values are not dividable into distinct units. -
ANSWER-continuous
A string of terms that are connected by division, addition, and subtraction
operations. - ANSWER-expressions
