You ask specific questions and learn from the answers.

 

To start with if you are adding you can think of  a number inside a square root as like a letter

 

For example.

 

Hopefull you know that    \(x+y \) can not be simplified

 

In the same way       \(\sqrt2+\sqrt3\)       cannot be simplified.

 

But hopfully you also know that      \(1x+5x+y=6x+y\)

 

Likewise          \(1\sqrt2+5\sqrt2+\sqrt3=6\sqrt2+\sqrt3\)
