6,578 PointsMy solution... tried to apply the DRY principle
alert("Let's do some math!");
let num1 = +prompt("Please type a number");
let num2 = +prompt("Please type another number");
let message = `<h1> Math with the numbers ${num1} and ${num2} </h1>`;
message += `<p> ${num1} + ${num2} = ${num1 + num2}
<br>${num1} * ${num2} = ${num1 * num2}
<br>${num1} / ${num2} = ${num1 / num2}
<br>${num1} - ${num2} = ${num1 - num2} </p>`;
document.write(message);

231,210 PointsLooks really "DRY".
But be aware that using "+" to convert strings to numbers can have unexpected results. For one example, if an empty response is given (blank line) it won't cause an error and just treat it as if 0 was given.
