Verified answer

Answer:

1. 8

2. 56

3. 14

4. 22

5. 32

Step-by-step explanation:

1. ( 12 + 3 ) - 7 = N

   15 - 7 = N

   8 = N

2. 4 ( 6 + 8 ) = N

  4 ( 14 ) = N

  56 = N

3. 25 ÷ 5 = 9 = N

  5 + 9 = N

  14 =N

4. ( 18 - 4 ) + ( 5 + 3 ) = N

  14 + ( 5 + 3 ) = N

  14 + 8 = N

  22 = N

5. ( 6 ÷ 3 ) + ( 10 × 3 ) = N

  2 + ( 10 × 3 ) = N

  2 + 30 = N

  32 = N
