What is the difference between "knowing" and "understanding"?

Hello Andy !

You may know that 2 + 2 = 4. You have learned that at school with calculating.

But only if you know WHY 2 + 2 = 4 , than you understand the basics of calculation.

Knowing is related to learned facts.
Understanding is related to why things are what they are !

What is the difference between "knowing" and "understanding"?
You can know something, but to UNDERSTAND it is something different completely.

Knowing is simple, you realize it's there, and acknowledge it's existence without further thinking

But to understand is to realize something, acknowledge it, and know why or how it is what it is.

^ these answers are as simple and understandable as I can put it so that even I can understand what the hell I'm talking about. Hope this helps!

Good and well thought out answers above! But, the most sufficient answer may depend on the context in which andyhaus1057 means for the words to be used.
