I'm a bit confused about the concept of a zero. How can I understand it better?

A zero is a number that is equal to nothing, or in other words, something that doesn’t exist. In mathematics, there are many different types of zeros. For example, a real zero is a number that is equal to 0, and an imaginary zero is a number that is equal to 0i. These two types of zeros are very different from each other!
