Answer 1

1.   (3 − 8) + [5 − (−2)] = − 5 + (5 + 2)= − 5 + 7= 2

2.  9 : [6 : (− 2)] = 9 : (− 3) = −3

3.  27 + 3 · 5 – 16 = 27 + 3 · 5 – 16 = 27 + 15 − 16 = 26

4.  27 + 3 – 45 : 5 + 16 = 30 – 9 + 16 = 37

5.   (2 · 4 + 12) (6 − 4) = (2 · 4 + 12) (6 − 4) = (8 + 12) (2) = 20 · 2 = 40

6.   3 · 9 + (6 + 5 – 3) – 12 : 4 = 3 · 9 + (6 + 5 – 3) – 12 : 4 = 27 + 8 – 3 = 32

7.   2 + 5 · (2 · 3)³ = 2 + 5 · (2 ·3)³ = 2 + 5 · (6)³ = 2 + 5 · 216 = 2 + 1080 = 1082

8.  440 − [30 + 6 (19 − 12)] = 440 − [30 + 6 (19 − 12)] = 440 − (30 + 6 · 7)] = 440 − (30 + 42) = 440 − (72) = 368

9.  2{4 [7 + 4 (5 · 3 − 9)] − 3 (40 − 8)} = 2{4[7 + 4 (15 − 9)] − 3 (32)}= 2[4 (7 + 4 · 6) − 96] = 2[4 (7 + 24) − 96]= 2[4 (31) − 96] = 2 (124 − 96) = 2 (28) = 56

10. 21 + 8 + 3 = 32

11. 14 − 17 - 5 + 3 - 1 = −6
