Answer 2

Answer:

(i) 170

(ii) -189

Step-by-step explanation:

So you know the plus and minus rules of integer

if its (-) + (+) = whichever is the larger number

now in the first case 590 which is positive is bigger so we subtract and put the bigger sign

whereas in the second one 480 is bigger which is negative so the sign is neg

560 -390 = 170 (put the larger number sign)

480 - 291 = 189 (put the larger number sign)

Hope this helps you!
