i watched for 1 minute and 36 seconds, and learned this topic faster than a week of my crappy online school

I've spent multiple classes trying to figure this out and for some reason everything just clicked while watching this, the explanation that you work from inside out saved me :)

Thank you. I had a problem like this on Lumen with no video for guidance. This saved me!

Not even 1:15 in, and I already know how to do this, when I spent an entire half-hour looking at examples and the stub that is the textbook explanation for this, *with* help from my father who is a literal highly-educated medical lab manager with extremely good math skills being completely lost.

[mahabaig]

thank you, you made it look so simple

I’m late but thanks for explaining this better than my teacher did
