An Actual Calculator

It is mind blowing how no one has created a calculator where you just type in an expression and get the result. All of the calculators I've seen have you type in one number then press enter then type in +, -, / or * then press enter then type your second number. This calculator takes simple expressions and returns the result.

Input:1+1 | Output:2
Input:1000-15 | Output:985
Input:10*10 | Output:100
Input:100/10 | Output:10
Input:2/3 | Output:0.666666
Input:0/0 | Output: Error

*No spaces in expressions
**Can do addition, subtraction, multiplication, and division. Planning to add more operations in the future.
***Has float/int switcher in division. If is not a whole number it is a float, if it is a whole number it is an int.
