Let him do all of it

But it's just algebra...

Yes I know its "Just algebra" And I would rather be taking that instead of differential equations ,but that wont happen now will it, and he'll be thinking the same thing when he starts taking algebra and he'll be wishing that he was still learning multiplication tables

I doubt he can find x

He can barely find his shoe

Or socks

Why do people cry if it's fun

Tears of joy?

lol if hes still struggling at algebra when he's 16 he should just be a barista or something

...that's a very promising thought...
