Step 1

Write down PEMDAS.

Step 2

Rewrite the expression to be evaluated.

P

MD

AS

(5 - 8)² + (-36) ÷ 6 x 2

Step 3

Substitute values for variables, if necessary.

(5 - 8)² + (-36) ÷ 6 x 2

Step 4

Ask yourself, "Are there any

parentheses ( ), brackets [ ], absolute values ||, or fraction bars?"

If yes, evaluate the expression in the parentheses.

Evaluate the expression in the parentheses.

If no, continue.

² + (-36) ÷ 6 x 2

Step 5

Ask yourself, "Are there any

exponents (powers or roots)?"

If yes, evaluate the power.

If no, continue.

Evaluate the power.

9 +(-36) ÷ 6 x 2

Step 6

Ask yourself, "are there any multiplication or division operations?"

9 + (-36) ÷ 6 x 2

If yes, evaluate from left to right.

If no, continue.

Divide!

**Evaluate the expression when**

a = 4 , b = -6, and c = -12.

a = 4 , b = -6, and c = -12.
