While they could solve problems given unlimited time and paper, their methods were impractical in real-world settings. Their math skills, though technically correct, were far too slow to be useful ...

It doesn’t stop there though. Most days, we are all faced with problems in real life that require us to apply some form of maths to help solve them.

Likewise, once you know the math laws or code syntax, you must apply them. Don’t just glance at solved problems — do them. Over and over. With pen and paper.
