|
associative property
|
property that states that
when you add or multiply, you can group numbers in any combination |
|
|
base
|
when a number is
written in exponential form, the number that is used as a factor is the base |
|
|
commutative property
|
property that states that
when you add or multiply, you can do so in any order |
|
|
distributive property
|
property that states that
number times a sum equals the sum of the products of that number and each addend |
|
|
exponent
|
a number that
tells how many times to multiply the base by itself |
|
|
identity property
|
property
that states that the product of 1 and a number and the sum of 0 and a number is that number |
|
|
numerical expression
|
an expression made up of
numbers and operations |
|
|
order of operations
|
the rules that must be
followed when simplifying expressions |
|
|
power
|
a number written
as a base and an exponent |
|
|
scientific notation
|
a type of shorthand for writing
large numbers |
|
|
Commutative Property
|
Add or multiply.
You can group a + b= b + a the numbers in any order. k . m = m . k |
|
|
Associative Property
|
When you add or multiply, you can group the numbers
(p + s) + t = p + (s + t) (x.y).z = x.(y.z) (p + (s t ) together in any combination. (x • y) • z |
|
|
Identity Property
|
The sum of 0 and any number is the number. The product of 1 and any number is the number.
x + 0 = x x . 1 = x |
|
|
Distributive Property
|
A multiplier outside the parentheses of another operation can be applied to each number inside the parentheses before the operation is performed.
d(e+f)= d(e)+ d(f) |
|
|
addition property of
equality |
you can add the
same value to both sides of an equation and the statement will still be true |
|
|
algebraic expression
|
an expression that
consists of constants, variables, and operation |
|
|
coefficient
|
the numerical
factor in a term containing a variable |
|
|
constant
|
a number in an
expression that does not change |
|
|
division property of
equality |
you can divide
both sides by the same number and the statement will still be true |
|
|
equation
|
a mathematical
statement that says two expressions are equal in value |
|
|
evaluate
|
substitute a
number for a variable in an algebraic expression |
|
|
inverse operations
|
operations that undo each
other |
|
|
multiplication property
of equality |
you can
multiply both sides of an equation by the same number and the new equation will have the same solution |
|
|
solution
|
the value of the
variable that makes the statement true |
|
|
subtraction property of
equality |
you can subtract
the same number from both sides of the equation and the new equation will have the same solution |
|
|
term
|
a number, variable,
or a product of numbers and variables |
|
|
variable
|
a number that is
represented by a letter because its value can change or vary |
