How do you do order of operations with parethesis?

Answer 1

PEMDAS

Parentheses First

Exponents

Multiplication and Division

Addition and Subtract

So parentheses get priority.

e.g.: (5 - 1) x (4 - 2 ) = 4 x 2 = 8

In this case, you do what is inside the parentheses first, even though it's subtraction.

Nested (inside each other) parentheses go with the inner most parentheses first.

e.g.: ( 3 + ( 8 - 2 ) x 3 ) = ( 3 + 6 x 3 ) = 3 + 18 = 21

The basic rule here is to always solve what is inside the parenthesis first.
