Answer 1

Answer:

A. multiplication property of one (1)

B. additive property of zero (0)

Answer 2

According to the multiplicative identity property of 1, any number multiplied by 1, gives the same result as the number itself. It is also called the Identity property of multiplication, because the identity of the number remains the same.

the sum of any whole number and zero is the number itself. That is, zero is the only whole number that does not change the value (identity) of the number it is added to. The whole number 0 (zero) is called the additive identity or the identity element for addition of whole numbers.
