Another math question?

Question

okay so this isnt exactly for math but then theres a question like:

when the [math] book provides you with a sample proof, why do you think they frequently include a plan for proof?

you might not get it because you have to have a geometry math textbook.

thanks in advance!

Answer 1

Normally it's because there's a simple way through the proof that may not be instantly obvious and it's like giving someone a map to get to a destination.  You don't have to use it, but it can be a great help.

That's all, I think

Answer 2

I think it's because the mathematics book want to encourage the reader to observe certain mathematical features, and formulate them in connected ideas. This becomes especially important in higher level maths, where problem solving often becomes much more efficient if the individual can immediately notice important facts, and recognize the general path they need to take.
