Need help on the IF-statement

I mean...isn't the statement like this:

if (variable > 1 )
{
do somthing
}

So I guess adding another varaible it must go in:

if ( (......>...) && (.....!=....) )

Or do I need different parentheses for the 2 variables? Like this (just an example):

if ( [......>...] && [.....!=....] )
