Calculator Module

This module provides basic arithmetic operations such as addition, subtraction, multiplication, and division.

Functions:

• add(a, b): Adds two numbers a and b and returns the result.
• subtract(a, b): Subtracts b from a and returns the result.
• multiply(a, b): Multiplies a by b and returns the result.
• divide(a, b): Divides a by b and returns the result.

Usage:

const calculator = require('./calculator');
console.log(calculator.add(5, 3)); // Output: 8
console.log(calculator.subtract(10, 4)); // Output: 6
console.log(calculator.multiply(2, 6)); // Output: 12
console.log(calculator.divide(10, 2)); // Output: 5
