Answer 1

a ) 2 × 3 : 1 - 1 × 3 × 2 =
6 : 1 - 1 × 3 × 2 =
6 - 1 × 3 × 2 =
6 - 3 × 2 =
6 - 6 =
= 0
c ) ( 5328 - 4758 - 500 ) × 3 =
( 570 - 500 ) × 3 =
70 × 3 =
= 210
e ) 66 : 3 + 83 × 11 - 50 × 10 =
22 + 83 × 11 - 50 × 10 =
22 + 913 - 50 × 10 =
22 + 913 - 500 =
935 - 500 =
= 435
b ) 68 : 2 - 33 : 3 + 12 × 2 =
34 - 33 : 3 + 12 × 2 =
34 - 11 + 12 × 2 =
34 - 11 + 24 =
23 + 24 =
= 47
d ) 58 : ( 1000 - 998 ) + 7 × 135 =
58 : 2 + 7 × 135 =
29 + 7 × 135 =
29 + 945 =
= 974
