“Oh, I get it….”

After finishing the dishes and making sure to eat some chocolate, too, we started our study session, more or less as planned at school.

I came up with example problems, had him solve them, and explained the method whenever he got one wrong.

It was a little harder than I’d expected to have to start by teaching him the formulas, but I was satisfied that he was following along so well.

If you memorized a few formulas, applying them was easy.

That method worked for middle school problems, anyway. Memorize a few formulas and try a few past exam questions, and you’d get the hang of it. High school problems were another matter.

“So, how do you think you should solve this one?”
