Treehouse Moderator 91,253 PointsThink this might be a bug, or else I don't understand Octal notaton yet. :)
I'm having trouble getting passed the second question in this challenge. It wants the value 16 in octal number notation.
Create a variable named "mevol" and assign the value 16 to it using an octal number literal.
I try
var mevol = 018;
But it comes up with
Bummer: octal notation is written like this var o = 021
I'm sure I'm doing it right, but I'm out of ideas as to what might be going wrong. Any thoughts?

If I haven't lost my mind yet, I believe the number you're looking for is 020

Treehouse Moderator 91,253 PointsYup, that's the one thank you! :)
Think I just need a bit of extra time on the numbers video to get octal numbers in the brain.

Treehouse Moderator 91,253 PointsLooking back at Octals again I could easily have worked out the answer with the club written in the comments haha But Octal numbers still confuse me. Probably best avoiding them altogether?
