Mass - ANSWER A measure of how much matter is in an object. Commonly measured by
how much something weighs. But weight can change depending on where you are (such as
on the moon) while this stays the same.
Prime Factorization - ANSWER Finding which prime numbers multiply together to make
the original number.
Associative Property - ANSWER Changing the grouping of numbers will NOT change the
value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication, (4 X 5) X 10 = 4 X
(5 X 10)
Distributive Property - ANSWER States that the product of a number and a sum is equal
to the sum of the individual products of addends and the number.
a(b + c) = ab + ac.
Commutative Property - ANSWER The order in which numbers are added or multiplied
does not change the sum or product.
Additive Inverse - ANSWER The opposite of the number. A number and its opposite add
up to give zero. They are called inverse additives of each other.
Greatest Common Factor (GFC) - ANSWER The greatest number that is a factor of each of
two or more given numbers.
Examples:
1
, The greatest common factor of 24 and 15 is 3.
The greatest common factor of 40, 50, and 25 is 5.
Supplementary Angles - ANSWER Supplementary angles are two angles that add up to
give a straight angle, 180°.
Expression - ANSWER A mathematical phrase that combines numbers and/or variables
using mathematical operations. An expression is a representation of a value; for example,
variables and/or numerals that appear alone or in combination with operators are expres-
sions.
Examples:
5 + 6 - (3 + 2)/18
a+b-c
Zero - Product Property - ANSWER States that if the product of two factors is zero, then at
least one of the factors must be zero
Ordered Pair - ANSWER A pair of numbers used to locate a point on a coordinate plane is
called an ordered pair.
An ordered pair is written in the form (x, y) where x is the x-coordinate and y is the y-coordi-
nate.
Area - ANSWER The amount of space inside the boundary of a flat (2-dimensional) object
such as a triangle, rectangle or circle. Different objects have different formulas to determine
area.
For a rectangle it is length X width.
