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.

*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.

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.

Examples:

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.

This calculator does it but uses external modules without actually coding it themself:

Shoutout to the creators of the calculators listed above for the idea and inspiration.

@proofofconcept: I don't know man, I put 2-1 into your calculator and I got -1. I also put 3/2 and I got nan. Regardless, I'm impressed.
