According to the identity property of addition, what happens when you add zero to a number?

The identity property of addition states that when you add zero to any number, the original number remains unchanged. This is a fundamental property of arithmetic that demonstrates how zero acts as the "identity" element for addition. When zero is added to a number, it does not affect the value of that number; hence, the sum is equal to the original number.

For example, if you take the number 5 and add zero to it, the result is still 5 (5 + 0 = 5). This property highlights the unique role of zero in addition, as it ensures that the value of other numbers remains intact and serves as a foundation for more complex mathematical concepts.
