Answer 1

F.

[55•5-(199-99•2+20•5)+220:10]:4

[275-(199-198+100)+22]:4

[275-(1+100)+22]:4

(275-101+22):4

(174+22):4

196:4=49

H.

9+8•[7+6•(5+4•3)-2•1]-10•10

9+8•[7+6•(5+12)-2]-100

9+8•(7+6•17-2)-100

9+8•(7+102-2)-100

9+8•(7+100)-100

9+8•107-100

9+856-100

9+756=765

J.

6+3•[18:3-3•(12:3-3)]:9

6+3•[6-3•(4-3)]:9

6+3•(6-3•1):9

6+3•(6-3):9

6+3•3:9

6+9:9

6+1=7
