Question

When we add zero to any whole number, we get the same whole number. Zero is an additive identity for whole numbers. Is it an additive identity again for integers also?Observe the following and fill in the blanks:
(i) (– 8) + 0 = – 8
(ii) 0 + (– 8) = – 8
(iii) (–23) + 0 = _____
(iv) 0 + (–37) = –37
(v) 0 + (–59) = _____
(vi) 0 + _____ = – 43
(vii) – 61 + _____ = – 61
(viii) _____ + 0 = _____

Answer 1

Answer:

yes, 0 is an additive identity again for integers also.

Step-by-step explanation:

(i) (– 8) + 0 = – 8  

(ii) 0 + (– 8) = – 8

(iii) (–23) + 0 = -23  

(iv) 0 + (–37) = –37

(v) 0 + (–59) = _-59____  

(vi) 0 + __-43___ = – 43

(vii) – 61 + __0___ = – 61  

(viii) _any integer____ + 0 = any integer_____
