What is the result of adding zero to any number?

Adding zero to any number yields the initial number itself, making the result equal to that number. This principle is rooted in the properties of addition, specifically the identity property of addition, which states that when you add zero to a number, the value of that number remains unchanged.

For example, if you take the number 5 and add zero, the result is 5 (5 + 0 = 5). Similarly, for any number you choose, this property holds true. This foundational concept is crucial in arithmetic and forms the basis for more complex mathematical operations, thus reinforcing why the correct answer accurately reflects this essential characteristic of addition.
