Answer 1

9 x ( 968 : 8 ) + 6540 - 5978 =
= 9 x 121 + 6540 - 5978
= 1089 + 6540 = 5978
= 1651
( 408 : 4 + 506 - 316 ) x 0 =
= ( 102 + 506 - 316 ) x 0
= 292 x 0
= 0
( 135 x 4 ) + ( 274 x 8 ) + ( 2 x 80 + 40 ) : 5 =
= 540 + 2192 + 200 : 5
= 540 + 2192 + 40
= 2772
( 3 x 167 ) - ( 3 x 153 )+( 450 x 2+12 ) : 9=
= 501 - 459 + 912 : 9
= 501 - 459 + 101,33
= 42 + 101,33 = 143,33
