Question

d) 28+{13-[6-(4+1)+2]}

e) {36-2+25+[18-(5-2)]}

f) {50-[2+(6-3)]+53

Answer 1

d) 28+{13-[6-5+2]}
28+{13-[3]}
28+{13-3}
28+10
38
e){36-2+25[18-(5-2)]}
{36-2+25[18-(3)]}
{36-2+25[18-3]}
{36-2+25[15]}
{36-2+25+15}
74
f) {50-[2+(6-3)]+53
 {50-[2+(3)]+53
{50-[2+3]+53
50-5+53
98

Answer 2

d) 28 + {13 - [6 - (4+1) + 2]} =
    28 + { 13 - [6-5+2]} =
    28 + { 13 - [3]}=
    28 + 10 =
    38

e) {36 - 2 + 25 + [18 - (5-2)]} =
     {36 - 2 + 25 + [18 - 3]} =
      {36 - 2 + 25 + 15} =
      74

f) {50 - [2+(6-3)] + 53} =
   {50 - [ 2 + 3] + 53} =
   {50 - 5 + 53} =
   98
