Answer 1

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
