No matter where PHP funtions work same.

Sir it does matter for me.. because i had bought one plugin and that is working others theme but not with mine zara theme.. why so?? How to fix this math functioning?

@Nancy
If you have problems with math functions, contact PHP developers.
Regarding plugin, you wrote nothing. What plugin? What does not work? How to replicate issue?
