In this project I have tried to create a Calculator which is diffrent from other calculators because instead of performing calculation for one command (like addition,subtraction,multiplication and divide) it can be used to calculate a whole equation at a time.

It does not matter how many numbers you are going to type in input. It can calculate a equation at a time like example. Eg.(26*12+45-78).

If you want to exit the calculator, you can directly type in the input box to exit the program.
