CH 13: I Will Never Use This
One of the most common phrases that a math teacher is likely to hear is the classic, "Why are we bothering to learn this, I will never use any of this in real life!"

This means your brain is better prepared to problem solve, and can you think of any areas in life where problem-solving ability might come in handy?” Besides the mental exercise aspect, it is no small fact that our entire world runs on numbers, applied though it may be. It is the language of the universe, of our cosmos.
