How to use
This program solves simple mathematical equations.  All answers are going to be rounded to the nearest integer.  
After solving, the program will output the equation and answer in LaTeX format to the same textbox as is used by input.  
All input methods can be used individually or in combination with the others.


To use button commands:
Click the buttons that correspond with the mathematical formula to be solved. 
Once the equal buttons is pressed, the Calculator will attempt solve the equation. 
If the equation is unsolvable or unrecognizable, the answer will be returned as “error”.  
“Clear” will clear the entire equation from the calculator while “Backspace” will delete the last character.  
The voice picture button toggles voice commands on or off.


To use keyboard commands:
The keyboard will accept any number or mathematical operator along with the ‘c’ keyboard button, which clears the calculator, 
and the ‘Backspace’ keyboard button that deletes the last character.  Once again, once the ‘=’ keyboard button is pressed, 
the calculator will attempt to solve the equation.  Also, ‘quit program’ will exit the program.


To use voice commands:
Below is a list of acceptable commands once the voice input is initialized by either clicking the voice button or saying 
“toggle voice”.
