Answer 1

34 - 2 × ( 19 - 8 : 2 ) = 34 - 2 × ( 19 - 4 ) = 34 - 2 × 15 = 34 - 30 = 4

________________________________________________

85 + ( 243 × 0 + 7 ) : 1 = 85 + ( 0 + 7 ) : 1 = 85 + 7 : 1 = 85 + 7 = 92

_________________________________________________

( 336 - 18 × 4 ) : 12 + 6 × ( 245 + 3 × 5 - 17 × 9 ) : 107 = 28

= ( 336 - 72 ) : 12 + 6 × ( 245 + 15 - 153 ) : 107 =

= 264 : 12 + 6 × ( 260 - 153 ) : 107 =

= 22 + 6 × 107 : 107 =

= 22 + 6 =

= 28

2 277 : ( 384 - 17 × 18 + 3 × 7 ) × 70 - 780 : 15 = 1 558

= 2 277 : ( 384 - 306 + 21 ) × 70 - 52 =

= 2 277 : ( 78 + 21 ) × 70 - 52 =

= 2 277 : 99 × 70 - 52 =

= 23 × 70 - 52 =

= 1 610 - 52 =

= 1 558

( 560 - 324 : 36 × 12 ) : 226 + 24 × ( 25 × 14 : 35 + 176 ) : 31 = 146

= ( 560 - 9 × 12 ) : 226 + 24 × ( 350 : 35 + 176 ) : 31 =

= ( 560 - 108 ) : 226 + 24 × ( 10 + 176 ) : 31 =

= 452 : 226 + 24 × 186 : 31 =

= 2 + 144 =

= 146
