### EQ

CCCA Unit 1

• 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

• Sum

• Plus

• More Than

• Increased

• Together

### SUBTRACTION

• Difference

• Minus

• Decreased

• Less Than (swaps the order)

• Take away

• Quotient

• Half

• Divide by

• Product

• Twice

• Double

• Triple

• Times

### EXPONENTS

• Square

• Cubed

• To the power of

• Raised to a power

### Translate

The sum of a number and 10

x + 10

### Translate

The product of 9 and x squared

9x2

### Translate

9 less than g to the fourth power

g4 – 9

### Translate

8 + 3x

Eight increased by three times a number
