JavaScript uses assignment operator ( = ) to assign values to variables. For example, by assigning var x = 5; and var y = 6; the value of x + y will be 11. The script may look like this:
<script>
var x = 5;
var y = 6;
document.getElementById("demo").innerHTML = x + y;
</script>
JavaScript uses arithmetic operators ( + - * / ) to compute values, just like algebra. For example, (5 + 6) * 10 will give the value of 110. The script may look like this:
<script>
document.getElementById("demo").innerHTML = (5 + 6) * 10;
</script>
