Question

9. Give example for each of the following cases: a) Zero is the additive identity of whole
numbers b) The product of a non-zero whole number and its successor is even​

Answer 1

Step-by-step explanation:

a) additive identity of whole numbers states that if zero is added to any number, then the result will be the number itself...

=> a+0 or 0+a =  a

b)Let the non-zero number be 'x', and it's successor be 'x+1'

Lets take an example,

'x' = 2

'x+1'= 2+1 = 3

Product of non-zero whole number and its successor,

=> 2x3 = 6....

I hope you understand..
