Answer 1

30 + 4 x ( 36 : 9 + 3 x ( 20 + 8 x 42 : 2 ) = 30 + 4 x ( 36 : 9 + 3 x 188 ) = 30 + 4 x 568 = 30 + 2272 = 2302

9 x ( 101 x 1 + 111 : 1 ) - ( 85 - 7 x ( 36 : 9 + 63 : 9 )) = 9 x ( 101 + 111 ) - ( 85 - 7 x 11 = 9 x 212 - ( 85 - 77 ) = 1908 - 8 = 1900

2 + 2 x ( 2 + 3 x ( 2 + 202 : 2 - 306 : 3 ) = 2 + 2 x ( 2 + 3 x 1 ) = 2 + 2 x 5 = 2 + 10 = 12

Answer 2

30+4*{36:9+3*(20+8*21)}=
30+4*{36:9+3*(20+168)}=
30+4*(36:9+3*188)=
30+4*(4+564)=
30+4*568=
30+2272=2300
9*(101*1+111:1)=
9*(101+111)=
9*212=1908
