Math & Science ⇒ \left( and \right)

[GenisToii]

Hi!

I wanna know if there's some method to do innecessary to write "\left" and "\right" to "(" and ")" when, for example, I write a fraccion between them. O, if not, if I could simplify it somehow because I tried with \newcommand but it doesn't let me

Thanks!

The nath package does this for you. There may be some incompatibilities with amsmath though.

But "nath" what does? I didn't have to write \left and \right or simplificy it?
And which type of incompatibilities?
Anyway, thanks you very much!

Weel I tried it and make a lot of errors in my document so I won't use it. Also I search in internet some information and there's soem rules to use "nath". but thanks equally

I don't know what incompatibilities, I just read a comment at tex.stackexchange that nath "doesn't play well with amsmath", or something like that.

For parenthesis specifically there is a possible solution here.
