my solutnion to challenge no1

hello!

my solution is a bit different but seems to be working, could you tell me if it is acceptable?

function randomArea(lower, upper) {
  var lower = Math.floor(Math.random() * lower - 1 ) + 1;
  var upper = Math.floor(Math.random() * upper) + 1;
  return upper - lower;
}

thanks!

Perhaps your testing could be a bit more thorough. For example, try generating a number between 50 and 60 (*"randomArea(50, 60)").

And here's a hint: Math.random() should be called only once in the function.

You are right, thank you.

Tell me... because in the first video Dave said that programming is like writing a story using programming language and synthax. But so far its more like solving mathematical logics riddles. Is it going to be like that but harder? Learning languages has always been fairly easy for me, but math or physics wasn't. Do I have a chance to be a good prgrammer? Are there any skills and knowledge outside pure programming field that would help me become good programmer?

Thanks

Certainly some programming tasks will involve math, but not all do. And even those that require math are often satisfied by well-known and published formulas that you can look up.
