There was a challenge someone mentioned of implementing addition without using the `+` operator... CHALLENGE ACCEPTED!

apiAdd.js

function add(x, y) {
  const apiUrl = `https://api.mathjs.org/v4/?expr=${x}%2B${y}`;
  try {
    let xhr = new XMLHttpRequest(apiUrl);
    xhr.open('GET', apiUrl, false);
    xhr.send();
    return Number(xhr.responseText);
  } catch (ex) {
    console.log("Ya'll numbers fucky");
    return NaN;
  }
}
