// Usage
let calculator = new Calculator();
calculator.add(5, 3);
console.log(calculator.getResult()); // Outputs: 8
calculator.subtract(5, 3);
console.log(calculator.getResult()); // Outputs: 2
calculator.multiply(5, 3);
console.log(calculator.getResult()); // Outputs: 15
calculator.divide(6, 3);
console.log(calculator.getResult()); // Outputs: 2
