In worksheet on simplification, the questions are based in order to simplify expressions involving more than one bracket by using the steps of removal of brackets. This exercise sheet on simplifications has different types of questions that can be practiced by the students to get more ideas to simplify the expressions.

A. Simplify each of the following:

1. 3 - (5 – 6 ÷ 3)

2. – 25 + 14 ÷ (5 - 3)

3. 25 – (1/2){5 + 4 - (3 + 2 – 1 + 3)}

4. 27 - [38 - {46 - (15 - 13 - 2)}]

5. 36 - [18 - {14 - (15 – 4 ÷ 2 x 2)}]

6. 45 - [38 - {60 ÷ 3 – (6 - 9 ÷ 3) ÷ 3}]

7. 23 - [23 - {23 - (23 - 23 - 23)}]

8. 2550 - [51 0 - {270 - (90 - 80 + 70)}]

9. 4 + (1/5) [{-10 x (25 - 13 - 3)} ÷ (-5)]

10. 22 - (1/4) {-5 - (- 48) ÷ (-16)}

11. 63 - (-3) {-2 - 8 - 3} ÷ 3{5 + (-2) (-1)}

12. [29 - (-2) {6 - (7 - 3)}] ÷ [3 x {5 + (-3) x (-2)}]

B. Using brackets, write a mathematical expression for each of the following:

1. Nine multiplied by the sum of two and five.
