Answer 1

This should do it.

  function printSum(a, b) {
    return "X = " + (a + b);
  }

  var a = 2;
  var b = 5;
  var output = document.querySelector("#sum");
  var sum = printSum(a, b);

  output.textContent = sum;
  console.log(sum);

In your html

<div id="sum"></div>

Answer 2

Template strings can be made with ` ` symbols. For example, let's say you have variable let name = "bob"; . You can make a template string out of it with console.log(`Hello, ${name}`);
