What does this mean "var randomNumber = Math.floor( Math.random() * 6) + 1; "

So I understand that it gets a random number but random number up until how far up until does it randomize....sorry I forgot. And understand the rounding of , of what floor means then its times that value with six. Then the plus one to get the random number only above zero.

What is it exactly, what you don't understand?

Math.Random() creates a random number between, 0 and 0.9999999 time this by 6 and you will always get a number between 0 and 5, if you use Math.floor. Then you add +1 because you don't want a number between 0 and 5, but 1 and 6

Awesome. Thanks! David Schriever
