In this worksheet, we will learn how putting brackets in different places gives different answers.

Remember that with a string of operations, they must be done in the following order:

Brackets

Powers or indices

Multiplication and division

Adding and subtracting

Remember BIDMAS

__Example__

3 + 5 × 6 - 2 × 3 + 4

= 3 + 30 - 6 + 4 (multiplying first)

= 31 (adding and subtracting from left to right)

**If we put brackets in different places, we will get a different answer.**

(3 + 5) × 6 - 2 × (3 + 4)

= 8 × 6 - 2 × 7 (brackets first)

= 48 - 14 (multiplying next)

= 34 (subtracting)
