Which of the following represents the additive identity? ab = ba a · 1 = a a + b = b + a a + 0 = a

Option D

Answers:  

In the given identities a + 0 = 0 + a will represent the additive identity.

Solution:  

The additive identity says that if you add a real number to zero or add zero to a real number, then you get the same real number back.  This can be written as,

A + 0 = A

The number zero is known as identity element or the additive identity.

Let us understand the additive property using a example:

Let us consider the case 0 + 40 = 40, here 0 represents the identity value.

When we add zero to real number 40, we get the result as 40 which is the same number.

Hence, on the given options, the value a + 0 = a will represent the additive identity.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
