I just want to wrap the Math latex equation using any html tag. The string be like
y = x2 or (x = sqrt{y}) . For all (y geq 0), x is defined. Thus, y is set of all non-negative and real number. Hence, range is (y geq 0) or [0, ∞).
I want output like
y = x2 or <math>(x = sqrt{y})</math> . For all <math>(y geq 0)</math>, x is defined. Thus, y is set of all non-negative and real number. Hence, range is <math>(y geq 0)</math> or [0, ∞).

Answer
The pattern for equation seems like this:
((\()((?!(\()|(\))).)*(\)))
The prefix (\() and suffix (\)) are simple check for start and end of the equation.
The middle part ((?!(\()|(\))).)* count any character (.) (except n) unless by looking ahead “(?! ...)” the two character in front be one of ( or ).
The whole equation pattern are in (...), so it could be referred to as group1 or $1. So that should be substituted by:
<math>$1</math>
