  • 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
