Answer 1

28 + [50 – (24 – 2) -10 ] =

28+[50-22-10]=

28+18=46

c. 20 + [ 13 + (10 – 6) + 4] =

20+[13+4+4]=

20+21=41

d. 52 – { 12 + [ 15 – ( 8 – 4)]} =

52-{ 12+[15-4]}=

52-{12+11}=

52-23=29

e. 25 + { 12 + [ 2 – ( 8 – 6 ) + 2 ]} =

25+{12+[2-2+2]}=

25+{12+2}=

25+14=39

f. { [ ( 18 – 3 ) + ( 7 + 5) – 2 ] + 5 } – 12 =

{ [ 15+12-2]+5}-12=

{25+5}-12=

30-12=18

g. 65 – { 30 – [ 20 – ( 10 – 1 + 6) + 1 ]} =

65- {30-[20-15+1]}=

65-{30-6}=

65-24=41

h. 45 + { 15 – [ ( 10 – 8 ) + ( 7 – 4) – 3 ] – 4 } =

45+{15-[2+3-3]-4}=

45+{15-2-4}=

45+9=54

i. 40 + { 50 – [35 – ( 25 +5) – 1 ]} + 7 =

40+{50- [35- 30-1]}+7=

40+{50-4}+7=

50+46+7=103

j. 38 – { 20 – [ 22 – ( 5 + 3) + ( 7 – 4 +1)]}=

38-{ 20-[22-8+4]}=

38-{20-18}=

38-2=36
