Alternate answer

// declare program variables

let num1; let num2; let multiply; let addition; let devide; let subtract; const main = document.querySelector("main")

alert("Let's do some math!");

num1 = prompt("Please type a number");

//loop one for number

while (isNaN(num1) || num1 === ""){ num1 = prompt("That was not a number please type a number"); }

//loop two for number

num2 = prompt("Please type a second number that is not 0");

while (isNaN(num2) || num2 === "" || num2 === "0"){ num2 = prompt("That was either not a number or the number 0. Please type a number that is not 0"); }

//maths

addition = (+num1) + (+num2); multiply = (+num1) * (+num2); subtract = (+num1) - (+num2); devide = (+num1) / (+num2);

//statement

main.innerHTML = <h2>Math with numbers ${num1} and ${num2}</h2> <p>${num1} + ${num2} = ${addition}</p> <p>${num1} * ${num2} = ${multiply}</p> <p>${num1} - ${num2} = ${subtract}</p> <p>${num1} / ${num2} = ${devide}</p> ;

Any way of making the above simpler? I've added loops rather than the if statements so that we get an answer.
