EXAM REV QUESTIONS AND 100%
CORRECT ANSWERS!!
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.
