Answer 1

Step-by-step explanation:

a. Lets take a number, say 10

10 + 0 = 10

Adding 0 to the number gives the sum as the number itself, thus, zero is additive identity of whole numbers

b. Let's take three numbers, 2, 5, and 7

Multiplying the numbers with their successors, we get:

2 x 3 = 6

5 x 6 = 30

7 x 8 = 56

6, 30, and 56 are even numbers, thus the product of a non-zero whole number and it's successor is always even.
