  1. a, -92 – (-192 + 45 + 9)
    = -92 +192 -45 – 9 
    = 100 -45-9
    = 46 
    b, 23 + (-32 – 18 – 22) – (-6)
    = 23 -32-18-22 +6 
    = -9 -18-22+6 
    = -49 +6 
    = -35 
    c, -(-81 – 23 + 27) – (-41 – 100)
    = +81+23+27 +41+100
    = 104 +27+41+100
    = 272
     
    d, -(-87 + 12 + 320) – (-28 – 1 + 9)
    = +87-12-320+28+1-9
    = +75 -320 +28+1-9
    = -245 +28+1-9
    = – 225
    e, -(-35 – 6 – 90 + 12)
    = +35 +6+90-12
    = 131 -12 
    = 119
    g, 4 + (-29 – 14 + 32)
     = 4-29-14+32
    = -25 -14+32 
     = -39 +32
    = -7
