// --- Homework Problem #1: Divisibility Check ---
// Create a program that checks if y is divisible by 5 using modulo (%)
let y = 17; 
let remainder = y % 5;

if (remainder === 0) {
    console.log(y + " is divisible by 5.");
} else {
    console.log(y + " is NOT divisible by 5. The remainder is: " + remainder);
}

// --- Homework Problem #2: Sum of Variables ---
// Create three variables: a, b, and sum. Add them together and print.
let a = 15;
let b = 25;
let sum = a + b;

console.log("Variable a: " + a);
console.log("Variable b: " + b);
console.log("The total sum is: " + sum);
