Here's a complete solution:
"use strict"
let num1 = 20
let num2 = 6
console.log("Numbers:", num1, "and", num2)
console.log("Sum:", num1 + num2)
console.log("Difference:", num1 - num2)
console.log("Product:", num1 * num2)
console.log("Quotient:", num1 / num2)
console.log("Remainder:", num1 % num2)
console.log("Power:", num1 ** 2)
