Maths and Finance

Graduating with a MBA in financial analysis this spring, was wondering if i should take calc this summer at community college, how needed is it in the business world? I know in abstract economics its really good to have, but is it worth the time and money when applied?

Depending on what you want to do in the business world. If you're working with statistics, analysis, or modeling, you need calc, preferrably at an advanced level.

i.e. lots of models are based on accounting standards, which are plugged directly into mathematical equations, but you need calc to know the assumptions of a particular system of equations to know if that can be done correctly. Not all accounting standards meet the assumptions of all particular system of equations, and if they get plugged into one without the proper assumptions being met, you get an undefined or incorrect solution.
