Thank u very much, why didn't I think about step/floor function before >_<. Math class is real but I can't find and example of simple function in it (maybe because I don't understand the definition very well )

The fact that a simple function can only take on finitely many values makes me think of the amount of money in a bank account.

I've think of the function that uses to calculate the distance from A to B, which is not a straight line, but unfortunately, my prof have forgotten about this so I've studied the next subject . But thank u anyway
