2. Here we need to apply the integer law of addition that is ⇒

 (-) + (-) = (-)

 (+) + (+) = (+)

 (+) + (-) = (-)

 

   (i) (-41) + (-82) +72 = (-51)

   (ii) 59 + (-14) + (-73) = (-28)

   (iii) 382 + (-126) + (-464) = (-208)

   (iv) (-623) + (235) + (745) = (357)

   (v)  (-441) + (-354) + (-205) = (-1000)    

   (vi) (-625) + 925 + 100 + (-200) = 200

3. Additive inverse of a number is a number that sums up to 0.

For example ⇒ x + (-x) = 0

(i) Additive inverse of 52 is (-52) because 52 + (-52) = 0.

(ii) Additive inverse of (-86) is (86) because (-86) + 86 = 0.

(iii) Additive inverse of (-103) is (103) because (-103) + (103) = 0.

(iv) Additive inverse of (-1) is (1) because (-1) + 1 = 0.

(v) Additive inverse of (-23) is (23) because (-23) + (23) = 0.
