What you need to know before the exercises

In this lesson: Identify the operation to perform first and the subexpressions that make up an algebraic expression.

How to proceed: Do not ask for the value yet. First separate the blocks created by parentheses, then look at the operation connecting them from the outside.

You can already assume: Algebraic expressions and operation precedence.
