**Question 6**:

Solve 4 (8 + 14)(37 – 18) + 46

*4 (8 + 14)(37 – 18) + 46*

**Solution**:= 4(22)(19) + 46

= 4 × 22 × 19 + 46

= 1672 + 46

= 1718

**Question 7**:

Calculate the value of

113 + 6(47 – 4 × 9)

*113 + 6(47 – 4 × 9)*

**Solution**:= 113 + 6[47 – (4 × 9)]

= 113 + 6(47 – 36)

= 113 + 6(11)

= 113 + 66

= 179

**Question 8**:

Solve 128 + (9 × 4) – 318 ÷ 6

*128 + (9 × 4) – 318 ÷ 6*

**Solution**:= 128 + 36 – 53

= 164 – 53

= 111

**Question 9**:

Calculate the value of

62 × 15 – 40 + 68 ÷ 17.

*(62 × 15) – 40 + (68 ÷ 17)*

**Solution**:= 930 – 40 + 4

= 894

**Question 10**:

402 – ( ) = 78 – 6 × 8 ÷ 16.

Find the missing number in the box.

*402 – ( ) = 78 – 6 × 8 ÷ 16*

**Solution**:402 – ( ) = 78 – 48 ÷ 16

402 – ( ) = 78 – 3

402 – ( ) = 75

( ) = 402 – 75

( ) = 327

there’s something wrong with question 9. i think you we’re supposed to take (-40) + 4

and not 40 + 4. also the actual answer is 894, not 886

Thanks for pointing out our mistake.

We had done the correction accordingly.
