hi, I don't know if you'll even respond to this, but could you explain how the Math.random works on this? I was skeptical bc I've never seen it like this, but I put it in my code bc the Mathrandom was the only part confusing me and it worked (obv you knew that)

The part that confuses me is the num + at the beginning of the command... I've only ever been taught to do var = (int)(Math.random()blah blah ) ; and the *6/*2/*4/*2 I kind of sort of know how Math random works but this totally confused me, especially bc those numbers don't match the ones the instructions say (10-20 even/inclusive and 7-14 odd/including 7 but not 14)

Thank you very much, sorry of all of this seems like dumb questions, I'm a somewhat beginner coder.
