Evolve Calculator

Evolve Calculator is a simple JavaScript-based calculator that performs basic arithmetic operations such as addition and subtraction.

Project Structure

The project contains the following files:

• calculator.js: Contains the core logic for the calculator, including functions for setting numbers, setting the operation, and performing calculations.
• index.html: The HTML file to provide a user interface for the calculator (not yet implemented).

Features

• Add two numbers.
• Subtract two numbers.

Usage

1. Set the first number using the setNumber(number) function.
2. Set the operation using the setCalculation(c) function, where c can be "+" for addition or "-" for subtraction.
3. Set the second number using the setNumber(number) function.
4. Call the calculate() function to perform the operation and get the result.

Example

setNumber(5); // Set the first number
setCalculation("+"); // Set the operation to addition
setNumber(3); // Set the second number
console.log(calculate()); // Outputs: 8

Future Enhancements

• Implement a user interface in index.html.
• Add support for more operations such as multiplication and division.
• Improve error handling and input validation.
