Nah im just revising

[@Miaphysite3]

I have finished all school-level math while I was in my country, but because of political and economic situations of my country I had to flee it with all my family and so I was out of school for so long as it was so upheaval, now I am starting GCSE this year just for the sake of doing them to have the “paper” qualification to apply for higher level, I think I will smash it to A* and I am using your videos to refresh my memory of math as it was my only and only favourite subject, maybe history was after math my little bit favourite.
Thank you.

Crossed positive 1 on the side of y and X was either equal or more then two 2X on that spot was correct

I always get confused with which line to use for and

[@as.albazzaz]

I like to see that greater than or equal to/less than or equal to have a line under them, meaning i add a dark line, and the normal ones without the equal to dont have lines underneath them, meaning theyre weak and dotted haha
