Answer 1

1] -17 - ( -24 ) : 3 + 6
= -17 + ( 24 : 3 ) + 6
= -17 + ( 8 + 6 )
= -17 + 14
= -3

2] -4 × 9 : 6 - ( -4 )
= ( -4 × 9 ) : 6 + 4
= ( -36 : 6 ) + 4
= -6 + 4
= -2

3] 42 : ( -7 ) × 5 + ( -2 )
= ( 42 : ( -7 )) × 5 - 2
= ( -6 × 5 ) - 2
= -30 - 2
= -32

4] -20 + 6 × ( -7 ) - ( -12 )
= -20 + ( 6 × ( -7 ) + 12
= -20 + ( -42 ) + 12
= -62 + 12
= -50

5] 100 - ( -8 ) × 5 + 25
= 100 + ( 8 × 5 ) + 25
= 100 + ( 40 + 25 )
= 100 + 65
= 165
