## Line Calculator

This program provides an easy-to-use, yet powerful numeric calculator. It let's you enter the computation "by hand" instead of by pressing buttons, including any level of parenthesis. In addition, you can store results of your computation in "variables" which you can use for further computations.

For example, start the program and enter the following computations:

-10 * (2.4 - Pi) [ENTER]

angle = 45 [ENTER]

sin(radians(angle))^2 + cos(radians(angle))^2 [ENTER]
