Marcus, sometimes it seems out of reach. Some people get it faster, some (like me), get it slower. But, when I don't get something I just keep coming back to it. If it was easy-Everyone would be doing it. This stuff can be pretty hard sometimes. Breathe.

The math can seem a bit tricky at first, but take it one step at a time.

First, you're going to adjust your function to take two arguments.
Then, the math.random function spits out a number between 0 and 1, so you need to multiply that by the difference of your arguments + 1.
We'll need the floor of that number (hence the +1) to get back an integer.
After that you'll add the lower argument and return it. This can all be done in one statement.

^^ mkmk is spot on. Right it in "psuedo code" first.

1.) create a random number 2.) check if they guessed the right number 3.) if not check if they were too high or too low 4.) Tell them they were too high or too low 5.) check their next guess

and so on. It's not that you need to be a prodigy but you DO need to put the work in. If you just want to follow a course and be a programmer i'll save you the time and let you know that is not going to happen.

But if you are willing to put in the work you can definitely get the knowledge/understanding to make apps, get a job or freelance.

Find a local meetup or a group that meets up and hang out with like minded people that will help you SOOOOOO much.

a little harsh about putting the work in, but your layout of how to solve the issue was nice. (if he made it this far in the course he obviously is willing to put the work in)

Well I didn't know where to start either. When you're new to programming sometimes you just don't know where to even begin. I started watching the video where he shows what he did and the second it made sense I stopped the video and started doing on my own. There's so many different things to learn when it comes to JavaScript especially that it's hard for some of us to remember it all.
