Answer 1

128+54:6=
128+9=137

(199+1)-3•7=
200-3•7=
200-21= 179

100-(8•8:8)=
100-(8•1)=
100-8=92

2•8+56:7=
2•8+8=
16+8=24

7•(46-38)=
7•8=56

45+20:4-3•5=
45+5-3•5=
45+5-15=
50-15=35

(10+13)+(36:9-21:7)=
23+(4-3)=
23+1=24

(5•4)+(45-2•9•6•0)=
20+(45-0)=
20+45=65

164+(100-9:9-5•10)=
164+(100-1-5•10)=
164+(100-1-50)=
164+49=213

5•(10:10•10)+(8•3-23)=
5•(1•10)+(24-23)=
5•10+1=
50+1=51

48+(103-100)•9+(24:3•0)=
48+3•9+0=
48+27=75
