 Exercise 1M

Question 1

Solution: 6 + (2x 5)

= 6 + 10

= 16

Question 2

Solution: (6 + 4) x 5

= 10 x 5

= 50

Question 3

Solution: 3 + (6 + 8)

= 3 + 14

= 17

Question 4

Solution: (10 – 3) + 13

= 7 + 13

= 20

Question 5

Solution: 18 – (3 + 7)

= 18 – 10

= 8

Question 6

Solution : (8 x 15) – 20

= 120 – 20

= 100

Question 7

Solution : 27 – (6 x 4)

= 27 – 24

= 3

Question 8

Solution: $30 –\left(\frac{112 }{14}\right)$

= 30 – 8

= 22

Question 9

Solution: $\frac{(35 – 15)}{ 4}$

$= \frac{20 }{ 4}$

= 5

Question 10

Solution: $\frac{80}{5\times 4}$

$=\frac{80 }{ 20}$

= 4
