5
Algebraic Expression Can have variables, numbers, addition, subtraction, multiplication, division, parenthesis, square roots, exponents… Examples:
6
Variable Symbols or letters used to represent an unknown Examples:
7
Term How many items are being added, subtracted, divided Examples: 3 4
8
Like Terms Same variable raised to the same power Examples:
9
Coefficient The number in front of a variable Examples: 123 9 1
10
Exponent 3 1 4 The number up in the air next to a base
The number of times you multiply something times itself Examples: 3 1 4
11
Base 2 x y What the exponent sits on
The part that has been raised to a power Examples: 2 x y
12
Constant -42 5 -8 A number that has no variable
It can be positive or negative Examples: -42 5 -8
13
Factors 1 and 6…. Or 2 and 3 9 and x and y (x + 2) and (y – 3)
Items that are being multiplied together Can be numbers, variables, parenthesis Examples: 1 and 6…. Or 2 and 3 9 and x and y (x + 2) and (y – 3) 3 and (z – 9)
14
Order of Operations -18 Simplify inside parenthesis
Take care of exponents In order from left to right, multiplication or division In order from left to right, addition or subtraction Examples: -18
