I don't know why we add +random1 at the end of the syntax.

231,275 PointsThat's the way the formula for a random pick works.
The formula is: "(random * range) + minimum
" where range is: "maximum - minimum + 1
".
But that would mean your numbers are out of order, plus you need parentheses to override the operator precedence. So your code should probably be:
math.floor(math.random() * (random2 - random1 + 1)) + random1;

5,561 PointsI believe that without the +random1 at the end, the number would be outside of the range.
Imagine is your numbers were 75 and 100. The difference is 25.
You would get something like .82929299 * 25 + 1
The result is not between 75 and 100. If you add 75 back in (ie, add random1), your number will be between 75 and 100.
