I have written a snippet of code in javascript, for a prompt to appear when clicked. I want to be able to enter a simple math problem (i.e. 230/2) and have it output the answer, rather than the math problem I just entered. Your help will be much appreciated.
<!DOCTYPE html>
<html>
<body>
<button onclick="myFunction()">Click me</button>
<p id="demo"></p>
<script type="text/javascript">
function myFunction()
{
var x;
var mathProblem=prompt("Enter your math problem","");
if (name!=null)
{
x = mathProblem;
document.getElementById("demo").innerHTML = x;
}
}
</script>
</body>
</html>
