It’s the “distance” between the lowest and highest points of your range. It doesn’t make sense to explain it out of context, so I’ll explain the whole thing.

If `min` is `2` and `max` is `5`, the “distance” from each other is `5 - 2 + 1 = 4`. Then multiplying that by the result of `Math.random()` (a number from `0` up to, but not including `1`), you’ll get a number from `0` up to, but not including `4`.

Now you plug that number to the `Math.floor` function, which drops the decimal part of the number (if it’s positive), so you now have the integers `0`, `1`, `2` and `3`.

At the end, you add the value of `min`, so you now have the integers `2`, `3`, `4` and `5`, which are all of the integers in the range from 2 to 5.

If you removed the `+ 1` from `(max - min + 1)`, you’ll only get the integers `2`, `3` and `4`, which is fine if you don’t want to include `max` in the numbers that you want to get.
