# the sum of any number and 0 is ?

## a+zero=a

## 1 + 0 = 1

2 + 0 = 2

3 + 0 = 3

If you add 0 (nothing) to a number what do you get?

## The sum of any number and zero is equal to the original number. This is because the addition of zero does not change the value of the number. To understand why, you can think of it as adding nothing to the number, so the number remains the same.

For example:

- If you have the number 5 and add 0 to it, the sum is 5.

- If you have the number -3 and add 0 to it, the sum is -3.

- If you have the number 0 and add 0 to it, the sum is still 0.

So, regardless of the number you are starting with, adding zero to it will always give you the same number as the sum.
