Answer 1

100 - 100 : 100 x [100+100 : 10 - (100 -75 : 25)]= 87 
= 100 - 1 x [ 100 + 10 - ( 100 - 3) ] = 
= 100 - 1 x ( 110 - 97 ) =
= 100 - 1 x 13 =
= 100 - 13 =
= 87 


 50 + 12 x [ 214 - 240 : ( 16 - 2 x 5 )] - 10 x 100 =1 138 
= 50 + 12 x [ 214 - 240 : ( 16 - 10 ) ] - 10 x 100 =
= 50 + 12 x ( 214 - 240 : 6) - 1 000=
= 50 + 12 x ( 214 - 40) - 1 000=
= 50 + 12 x 174 - 1 000 =
= 50 + 2 088 - 1 000=
= 2 138 - 1 000
= 1 138 


 110 x 10 - [ ( 599 - 99 x 4 + 30 x 5 ) + 370 :10] : 10 = 1 061 
= 1 100 - [ ( 599 - 396 + 150 ) + 37 ] : 10 =
= 1 100 - [ ( 203 + 150 ) + 37] : 10 =
= 1 100 - ( 353 + 37 ) : 10 =
= 1 100 - 390 : 10 =
= 1 100 - 39 = 
= 1 061 


 ( 9 x 999 - 999 : 9) : 10 - [444 - 6 - (400 - 400 : 10 ) ] = 810
= ( 8 991 - 111 ) : 10 - [ 438 - ( 400 - 40 ) ] =
= 8 880 : 10 - ( 438 - 360) =
= 888 - 78 =
= 810
