Question

13. The difference of a given number and 0 is the what itself
​

Answer 1

The difference of a given number and 0 is the number itself.

Concept:

Let b be a number such that when added with another number a, the result is the number itself, that is, a + b = b + a = a, then b is called the additive identity.

However for subtraction, only one such condition is possible, which is a - b = a, but b - a = - a.

Step-by-step explanation:

Let the given number be p.

Then, p - 0 = p, the number itself.

Also, 0 - p = - p, the negative of the number.

So, the required difference is p since the question has mentioned the number before and 0 later.
