Front

What is the purpose of parentheses in an expression?

Back

Parentheses indicate which operations should be performed first.

Front

What do you do if there are multiple operations of the same rank, like multiplication and division?

Back

You perform them from left to right.

Front

What is an example of an expression that requires the order of operations?

Back

An example is 2 + 3 x (4 - 1).
