EXERCISE 25

(1) 28 – 3 × 5 + 4

= 28 – 15 + 4

= 13 + 4

= 17

(2) 42 – 18 ÷ 2 × 3

= 42 – 9 × 3

= 42 – 27

= 15

(3) 15 – 3 × 4 ÷ 2 – 2

= 15 – 3 × 2 – 2

= 15 – 6 – 2

= 15 – (6 + 2)

= 15 – 8

= 7

(4) 36 ÷ 6 + 3 × 2

= 6 + 6

= 12

(5) 27 + 8 ÷ 4

= 27 + 2

= 29

(6) 8 – 0 ÷ 5

= 8 – 0

= 8

(7) 8 × 8 – 6 × 6

= 64 – 36

= 28

(8) 5 ÷ 5 + 6 × 6

= 1 + 36

= 37

(9) 7 × 4 – 12 ÷ 6 – 8

= 28 – 2 – 8

= 28 – (2 + 8)

= 28 – 10

= 18

(10) 25 ÷ 5 – 16 ÷ 8

= 5 – 2

= 3

(11) 8 – 30 ÷ 6 + 7

= 8 – 5 + 7

= 3 + 7

= 10

(12) 6 × 5 – 60 ÷ 15

= 30 – 4

= 26
