Ex 6.3,3 Fill in the blanks. (a) (– 8) + _____ = 0(− 8) + ____ = 0 ____ = 0 − (− 8) ____ = 0 + 8 ____ = 8 ∴ (− 8) + (8) = 0 Ex 6.3,3 Fill in the blanks. (b) 13 + _____ = 0 13 + ___ = 0 ___ = 0 − 13 ___ = −13 ∴ 13 + (−13) = 0 Ex 6.3,3 Fill in the blanks. (c) 12 + (–12) = ____ 12 + (−12) = ____ 12 + (−12) = 12 − 12 = 0 ∴ 12 + (−12) = 0 Ex 6.3,3 Fill in the blanks. (d) (– 4) + ____ = – 12 (− 4) + ____ = −12 ____ = −12 − (− 4) ____ = −12 + 4 Taking − common ____ = −(12 − 4) ____ = −8 ∴ (−4) + (−8) = −12 Ex 6.3,3 Fill in the blanks. (e) ____ – 15 = – 10 _____ – 15 = –10 _____ = –10 + 15 _____ = 15 – 10 _____ = 5 ∴ 5 – 15 = –10
