Notes:
It's okay and completely understandable you might not be able to understand Khan Academy much. We all have our own struggles. I highly recommend using Brainly more. It's a much bigger community, with millions of other users always online to help. Oh - and don't forget about the moderators! I heard they're always on the look out and super hungry for question answering!
A Brainliest or Thank You is always appreciated! Please make sure to rate this answer and Heart it so we can easily help grab more attention for any other users who might also need help.
Cheers,
Chris.
