Answer 1

36+24-10=50
70-36+42=76
22+8-30=0
48+12-20=40
60+(24-7)=77
50-(19+9)=22
 90-(50-11)=51
70-(25+5)=40
72-4+5=73
28+5-8=25
36+7-9=34

Answer 2

1) 60 - 10 = 50
2) 112 - 36 = 76
3) 30 - 30 = 0
4) 60 - 20 = 40
5) 60 + 17 = 77
6) 50 - 28 = 22
7) 90 - 39 = 51
8) 70 - 30 = 40
9) 77 - 4 = 73
10) 33 - 8 = 25
11) 43 - 9 = 34
