What is the meaning of integration under integral sign?

In simple :
Differentiation means division.
Integration means adding whole stuffs.
When studying Differentiation under integral sign, I just thought I am differentiating under integral just to solve the solution easily.

But, I can't understand what's the meaning of integration under integral sign.

Youtube says,"i Don't know". I haven’t search in using Search engine. I will add another comment after searching
