KS2 Primary Maths Age 13-17 - Calculations: Order of Operations - Explained

The video tutorial explains the BIDMAS rule, which stands for Brackets, Indices, Division, Multiplication, Addition, and Subtraction. It emphasizes the importance of following this order in mathematical calculations. The tutorial provides an example calculation involving indices and addition, demonstrating how to apply BIDMAS to solve problems correctly.

What is the correct order of operations in BIDMAS?

• Brackets, Addition, Division, Multiplication, Subtraction, Indices

• Brackets, Indices, Division, Multiplication, Addition, Subtraction

• Brackets, Indices, Multiplication, Division, Subtraction, Addition

• Brackets, Division, Indices, Multiplication, Addition, Subtraction

In the expression 6 squared, what is the result?

• 36

• 18

• 12

• 42

What is the next step after calculating 6 squared in the given example?

• Divide by 10

• Add 10

• Subtract 10

• Multiply by 10

What is the final result of the calculation 6 squared plus 10?
