(1) 23 -10 + 2
(ii) 33- 3x4
(iii) 60 - 3 4x2
(v) 8 7-6 x 3
(iv) 15 - 3+2
(i) 5 + 2 + 3 x 2 (vii) 6+ 10 = 2 (viii) 15+5 + 8 + 2
3. Simplify:
(1) 32- (8 + 14) - 7
(ii) (32-8) + (14-7) (iii) (16+8) +2 (iv) 16+(8-2)
(v) 23 - (6 x 3) - 4
(i) 24 x 8 + (4 – 2) (vii) (16+4) -(8-2) (viit) 2 (5-3) = 4
4. Simplify:
(1) [12 + (18+3)] -11 (ii) [16 - (9+3)] * 2 (iii) [13-(8-3)] +6 (iv) [16 - (12 + 4)] * 3
(v) 200 = [4 x (6+3)] (vi) [(12 * 3) + (12+3)]* 2
5. Simplify:
(1) 58 - [28 - {15 - (12-4+2 x 2)}]
(ii) 37

(ii) (28 -(8+2)] = (5+1) * 2)
(iv) 39 - [24 + (18-(15-5)1
6. Insert brackets wherever necessary to make the following true:
(1) 8-6* 3 = 6
(ii) 120 + 4x2 = 15 (iii) 120 + 4 x 2 = 60
(iv) 57-3-1 = 15 (v) 5x7 - 3+1 = 33 (0) 5 x7 – 3 – 1 = 19
(vii) 3+2 * 8 - 4 = 36 (viii) 3 +2× 8 -4 = 11 (ix) 3+2 x 8-4 = 15
