Expression Solver

Description

This applicaiton takes an expression as a string and solves it.

It is capable of handling parenthesis, exponentiation, multiplicaiton, division, addition and subtraction. The program also recognizes when a number outside of the parenthesis is touching the parenthesis, noting that this indicates multiplicaiton. All results return in whole numbers, rounded.
