Is learning math getting the answer the book gives when it’s wrong?

So we’re having this lively discussion on LINCS about that “challenge problem.”

Nobody can tell me why the bases have to be the same… but they’re all gamely trying to “help me understand” how to get to the solution.

Dudes.   I understand five different ways to get to the solution given.

All of those ways assume the bases are the same.

THe problem does not state that the bases are the same and, in fact, gives them different variables.

I find it fascinating that it seems the other assumption is that mathematical reasoning is totally and completely trumped by… What The Test Maker States Is THe Answer.   So, the GED is not a math test.   It’s a “can you get the answer the test maker got?” test.
