Parentheses in Math

In math, parentheses are used to indicate the order of operations in an expression. They are also used to group numbers or variables together to show that they should be treated as a single entity.

Order of Operations

When solving an expression that contains parentheses, you should always start by solving the operations inside the parentheses first. The order of operations is:

Parentheses
Exponents
Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)

Examples

Here are some examples of how parentheses are used in math:

Example 1: (3 + 5) × 2
Start by solving the operation inside the parentheses: 3 + 5 = 8
Then multiply the result by 2: 8 × 2 = 16

Example 2: 4 × (6 - 2)
Start by solving the operation inside the parentheses: 6 - 2 = 4
Then multiply 4 by the result: 4 × 4 = 16

Study Guide

Here are some key points to remember about parentheses in math:

Parentheses are used to indicate the order of operations.
Always solve the operations inside the parentheses first.
Remember the order of operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
Be careful when dealing with multiple sets of parentheses - work from the innermost set outwards.

Remembering these key points will help you correctly solve expressions that contain parentheses.

The resources above cover the following skills:

Geometry (NCTM)

Specify locations and describe spatial relationships using coordinate geometry and other representational systems.

Use coordinate geometry to represent and examine the properties of geometric shapes.

Use coordinate geometry to examine special geometric shapes, such as regular polygons or those with pairs of parallel or perpendicular sides.

Use visualization, spatial reasoning, and geometric modeling to solve problems.

Use geometric models to represent and explain numerical and algebraic relationships.

Measurement (NCTM)

Apply appropriate techniques, tools, and formulas to determine measurements.

Select and apply techniques and tools to accurately find length, area, volume, and angle measures to appropriate levels of precision.

Connections to the Grade 6 Focal Points (NCTM)

Measurement and Geometry: Problems that involve areas and volumes, calling on students to find areas or volumes from lengths or to find lengths from volumes or areas and lengths, are especially appropriate. These problems extend the students' work in grade 5 on area and volume and provide a context for applying new work with equations.
