Order of Operations - PEMDAS

Objective: I know how to perform mixed operations with parenthesis, exponents, multiplication, division, addition, and subtraction.

If the calculations involve a combination of parenthesis, exponents, multiplication, division, addition, and subtraction then

Step 1: First, perform the operations within the parenthesis

Step 2: Second, evaluate the exponents.

Step 3: Third, perform multiplication and division from left to right.

Step 4: Fourth, perform addition and subtraction from left to right.

Example:

Calculate 2³ – 3 × (8 – 6) =

Solution:

2³ – 3 × (8 – 6) (perform within parenthesis)

= 2³ – 3 × 2 (evaluate the exponent)

= 8 – 3 × 2(perform multiplication)

= 8 – 6 (perform subtraction)

= 2

We hope that the free math worksheets have been helpful. We encourage parents and teachers to select the topics according to the needs of the child. For more difficult questions, the child may be encouraged to work out the problem on a piece of paper before entering the solution. We hope that the kids will also love the fun stuff and puzzles.
