  • Evaluate 8 - g, when g = 3
    8 - (3) = 5
  • Evaluate 4w, when w = 5
    4(5) = 20
  • Evaluate 2rz - 9, when r = 2 and z = 5
    2(2)(5) - 9 = 20 - 9 = 11
  • Evaluate p + 9, when p=6
    (6) + p = 15
  • Evaluate 3(x + 4) - w, when x = 3 and w = 8
    3( (3) + 4 ) - (8) = 3(7) - 8 = 21 - 8 = 13
