Just do Andrew NG's course.

It will show you the maths, you'll build simple neural nets (from maths!) that can read digits and scale it from there.

While doing it, you may struggle with some of the maths, just take a deep breath and invest sometime to fill the gaps you need and continue.

Learn about CNNs and everything else step-by-step. It's awesome.

Andrew Ng's course is great for the learning NN's from scratch, but not understanding how NN's fit in the broader discipline of AI.
