I've tried many times to hear it again and again and I just don't get it. Is there any resource or someone who could explain it to me? the math was very confusing for me.

So similar to the first part of the challenge; the range (topNumber - bottomNumber + 1) represents the total number of numbers that can be chosen (ex. topNumber = 10; bottomNumber = 5 // range of numbers = 5, 6, 7, 8, 9, 10 is 6 choices, hence the + 1). This is then multiplied by the Math.Random() and then the floor is taken to get a value. The lowest possible value that could be calculated here is a 0 so to ensure that the result stays in the range you then add it to bottomNumber (ie 5) to return 5; The highest possible would be, say Math.Random() = .99 the floor of this multiplied by 6 would be 5 then added to 5 again returns 10.
Hope this helps!
