Answer 1

a) 7 - (1+3) =

7 – ( 4 ) =

11

b) 9 – (5 – 1 + 2 ) =

9 – ( 6 ) =

9 – 6 =

3

c) 10 – ( 2 + 5) + 4 =

10 – 7 + 4 =

3 + 4 =

7

d) ( 13 – 7 ) +8 –1 =

6 + 7 =

13

e) 15 – (3 + 2) –6 =

15 – 5 – 6 =

15 – 11 =

4

f) (10 – 4) – (9–8) + 3 =

6 – 1 + 3 =

5 + 3 =

8

g) 50 – [37 –(15–8) ] =

50 – [ 37 – 7 ] =

50 – 30 =

20

h) 28 + [50 – (24–2) – 10 ] =

28 + [ 50 – 22 – 10] =

28 + [ 50 – 32 ] =

28 + 18 =

46

i) 20 + [13 + (10 – 6 ) + 4 ] =

20 + [13 + 4 + 4 ] =

20 + 13 + 8 =

20 + 21 =

41

j) 52 – {12 + [15 –(8–4) ] } =

52 – {12 + [ 15 –4 ] } =

52 – { 12 + 11 } =

52 – 23 =

29

2.

[ ( 18 + 3 . 2 ) ÷ 8 + 5.3 ] ÷ 6 =

[ ( 18 + 6 ) ÷ 8 + 15 ] ÷ 6 =

[ 24 ÷ 8 + 15 ] ÷ 6 =

[ 3 + 15 ] ÷ 6 =

18 ÷ 6 =
