Might wanna move your hand out of the way and go slower. I had to pause the video a couple of times to be able to calculate because I couldn't see through your hand. This makes sense, but I would also say let's turn it into: w²-7+(a-a)= 5²-7+0=18+0 25+(-5-2)= 18 or 9(2). 3²-2+6w=9-2=7+30=35+2=37, so as to eliminate brevity and show all of the working parts.

To small can't see the numbers
