A number that can be written as a ratio of integers, which means it can be
written as a fraction. - ✔✔rational number
The result of multiplying values. - ✔✔product
A number whose value is 0 or greater and can be represented without a
fractional or a decimal component. - ✔✔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. - ✔✔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. - ✔✔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,... - ✔✔perfect square

,In mathematics: a collection of numbers. - ✔✔set
A set of rules that defines the order in which mathematical operations should
be performed - ✔✔order of operations
The number you must multiply x by to get 1. For example, 5 and 1/5. -
✔✔multiplicative inverse
The positive square root of a number. - ✔✔principal square root
A set of numbers between two specified values. - ✔✔interval
A word or symbol (such as + or -) that indicates an operation between values. -
✔✔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. - ✔✔commutative
The symbol which indicates to take the square root of the number that follows.
- ✔✔radical sign
Two numbers equidistant from 0 on a number line whose sum is 0. For example,
3 and -3. - ✔✔additive inverse
The greatest number that is both a factor of a and a factor of b. - ✔✔greatest
common factor (GCF)

, A graphical method used to identify the prime factorization of an integer. -
✔✔factor tree
A number, (positive, negative, or zero), that can be represented without a
fractional or a decimal component. - ✔✔integer
A collection of numbers whose values are distinct, separate, and unconnected. -
✔✔discrete
Determining the set of prime numbers whose product is the original integer. -
✔✔prime factorization
A collection of numbers whose values are not dividable into distinct units. -
✔✔continuous
A string of terms that are connected by division, addition, and subtraction
operations. - ✔✔expressions
The result of a division expression. - ✔✔quotient
Sometimes called a power, it is a quantity that represents repeated
multiplication. - ✔✔exponents
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. - ✔✔factor
