간편 한 계산: 1, 95 - 81 / 7.5 - 92, 9.99 / (50 * 1.11) 3, [8 + (0.5 - 0.2) / 1.2] * 0.24

1. 95.5 - 81 / 7.5 - 9.2
= 95.5 - 10.8 - 9.2
= 95.5 - (10.8 + 9.2)
= 95.5 - 20
= 75.5
2. 9.99 / (50 * 1.11)
= 9.99 / 1.11 / 50
= 9 / 50
= 0.18
3. [8 + (0.5 - 0.2) / 1.2] * 0.24
= [8 + 0.3 / 1.2] * 0.24
= [8 + 0.25] * 0.24
= 8 * 0.24 + 0.25 * 0.24
= 1.92 + 0.06
= 1.98
