Answer 1

To use function inside Another function you can call the function two inside function one like this example

function function_one() {
function_two();
console.log("The function called 'function_one' has been called.");
}

function function_two() {
console.log("The function called 'function_two' has been called.");
}

function_one();

Answer 2

It's called a nested/inner function and you call it inside the outer function, also using "×" for multiplication is incorrect use * 🙂
