*selesaikan perkalian dan pembagiannya dulu
1. 5 x (-18) - 80 : 16 + 7 = (5 x -18) - (80 : 16) + 7 = (-90 - 5) + 7 = (-95) + 7 = (-88).
2. -45 : (-3) + 8 x (-3) - 15 = (-45 : -3) + (8 x -3) - 15 = (15 + -24) - 15 = (-9) - 15 = (-24).
3. 6 + 8 x (-9) + 150 : 25 = 6 + (8 x -9) + (150 : 25) = (6 + -72) + 6 = (-66) + 6 = (-60).
4. 24 - 6 : 2 + 4 x (-7) = 24 - (6 : 2) + (4 x -7) = (24 - 3) + (-28) = 21 + (-28) = (-7).
5. 80 : 5 - 7 x (-9) - 9 = (80 : 5) - (7 x -9) - 9 = (16 + 63) - 9 = 79 - 9 = 70.
