What is understanding?

Understanding is terms of a noun is the ability to comprehend something and the definition of understanding as an adjective is sympathetically being aware of someone else's feelings. The understanding as a noun deals with an educational matter, being able to comprehend or understand something you learned. The second definition of understanding as an adjective deals with a personal kind of understanding. Understanding is different for everyone not only the meaning of it but also because of how people understand things. When I say how people understand things I mean how some students or nonstudents learn hands-on, verbally, and both; like me. These are a few ways how people understand things whether it is learning how to drive or learning how to solve an equation. When learning how to drive the traditional way to learn is by taking driving school but on paper but then you also need to try hands on because hands-on is way different than learning it on paper. Solving an equation is done by explaining how to do it but then after the explanation one must try solving another equation themselves. Another way understanding can be  done is simply be done by taking notes and studying them after. No matter who you are there is never one way to comprehend something new. There are more questions that lead to what understanding is for example it can lead to you asking what is correct? but at the same time what is incorrect? In this case we are just simply talking about what is understanding?
