Answer: HOPE IT HELPS
Step-by-step explanation:
5. 15 + [18 - {4 + (16 -5)}]
= 15 + [18 - {4 + 11}]
= 15 + [18 - 15]
= 15 + 3
= 18
6. 22 -(16 - (8 ÷ 4 + 2)}
= 22 - (16 - 4)
= 22 - 12
= 10
7. 18 - [18 – {18 - (18 - 18) - 18}]
= 18 - [18 – {18 - 0 - 18}]
= 18 - [18 – 0]
= 18 - 18
= 0
8. 150 - [70 - (60 – (30 + 20)}-10]
= 150 - [70 - (60 - 50) -10]
= 150 - [70 - 10 -10]
= 150 - 50
= 100
