Confused on the modulo bit

[Epic-Fafnir]

Explanation on the dice generator lesson why does it say max_number+1 confused on why that's there what it's supposed to do I know it limits the Randi function but how and the process of why. P.S The app has been really great stop using it for a while cause of exams and my laptop had to get fixed, really beginner-friendly as I am a beginner and allows you to learn at a great pace.

Let's say the max_number is equal to 5, by using randi() you'll have 0, 1, 2, 3, 4 numbers.

By adding 1, that is max_number + 1, each individual number would increase by 1:
from 0, 1, 2, 3, 4 now you have 1, 2, 3, 4, 5.

Here's another example:
