Wonderful! Yes, if you have two integers that come one after another, for example, $$1$$ and $$2$$, you cannot find another integer between them.
Integers are the opposite of continuous; they are discrete. You can only find integers between two integers if the integers don't come one after another. Otherwise, you can't.

For thousands of years, people wondered if matter was continuous or discrete. That is, if you take an object and keep splitting it into smaller pieces, will you get smaller and smaller pieces, like with real numbers?

Or, does this process of splitting stop until you can't split it anymore?
