• Why is it important to understand the “language” of mathematics?

### Definitions

Identifying Parts

Guided NOTES

Algebraic Expression
• Can have variables, numbers, addition, subtraction, multiplication, division, parenthesis, square roots, exponents…
• Examples:
Variable
• Symbols or letters used to represent an unknown
• Examples:

Term
• How many items are being added, subtracted, divided
• Examples:

3

4

Like Terms
• Same variable raised to the same power
• Examples:
Coefficient
• The number in front of a variable
• Examples:

123

9

1

Exponent
• The number up in the air next to a base
• The number of times you multiply something times itself
• Examples:

3

1

4

Base
• What the exponent sits on
• The part that has been raised to a power
• Examples:

2

x

y

Constant
• A number that has no variable
• It can be positive or negative
• Examples:

-42

5

-8

Factors
• 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)

Order of Operations
• 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
