To use the program, simply type a mathematical expression into the command prompt and press enter:

2 - 5 * 3 - (4 + 7^2) / 5

Which will result in this output:

Solution: -23.6

You must use the * symbol in order to multiply. My program will recognize (3) * (3) as multiplication, but it will consider (3)(3) to be invalid input.

To exit the program, type exit.
