Learning Objective
I can use parentheses in expressions.
Today we will learn how to use parentheses in expressions. Math helps us solve problems and understand the world around us.
An expression is a combination of numbers, variables, and operations (like +, −, ×, ÷). Unlike an equation, an expression doesn't have an equals sign. Examples: 3x + 5, 2(4 + 1), or 7 − 2. Expressions represent a value, and we can simplify them by following the order of operations. Think of expressions as mathematical phrases, while equations are complete sentences!
Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!
Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
