Expressions Involving Brackets and Fractions - JSS3 Mathematics Lesson Note

Expressions involving brackets and fractions are mathematical statements that include parentheses (brackets) to indicate the order of operations and fractions. Brackets help clarify which operations should be performed first.

Example 1: Simplify the expression 

3×(2+4)

First, solve the operation inside the brackets: 

2+4=6

Then multiply the result by 3: 

3×6=18

Example 2: Simplify 

3/4 ×(8+2)

First, solve the operation inside the brackets: 

8+2=10

Then multiply by 3/4: 

3/4 ×10 = 30/4 = 7.5
