Answer 2

Answer:

(1) 5

(2) -3

(3) 30

(4) -40

(5) -1

(6) -6

Step-by-step explanation:

In the given questions,

On calculating the values using BODMAS rule:

(1) 17 + (-12)

= 17 - 12

= 5

(2) (-18) +15

= -18 +15

= -3

(3) 12 - (-18)

= 12 + 18

= 30

(4) (-25) + (-15)

= -25 - 15

= -40

(5) (-9) - (-8)

= -9 + 8

= -1

(6) 14 - 20

= -6
