Why double ))

In the videos before there was a line of code which had 2 )) - parenthesis. Can I know why (secondNumber - firstNumber + 1))

Hey there,

Without seeing the whole code snippet, I can't say exactly where. But, if there are two closing parenthesis, then somewhere further back in the code, there will be a second opening one.

i.e, 

if (myNumber > (yourNumber - 20)) {
  // do something
}

You'll notice that I have an opening ( for the if block conditional, and an opening one for the conditional equation which is then closed and then the if block conditional is also closed, so you see )). There will always be the same number of closing ones as there are opening ones.

Hope that helps.
Keep Coding! :dizzy: :)
