JavaScript determine add, product of two numbers

In this section, you will learn how to determine addition, multiplication, division and modulus of two numbers. To find this, we have created two textboxes and four button for the corresponding functions. As the user clicks the button after entering the bumbers in their respective textboxes, the result will get displayed through the alert box.

Here is the code:

<html>
<script>
function add(){
var num1=document.form.text1.value;
var num2=document.form.text2.value;
var sum=Number(num1)+Number(num2);
alert("Sum of two numbers is: "+sum);
}
function divide(){
var num1=document.form.text1.value;
var num2=document.form.text2.value;
var sum=Number(num1)/Number(num2);
alert("Result is: "+sum);
}
function product(){
var num1=document.form.text1.value;
var num2=document.form.text2.value;
var sum=Number(num1)*Number(num2);
alert("Product is: "+sum);
}
function modulus(){
var num1=document.form.text1.value;
var num2=document.form.text2.value;
var sum=Number(num1)%Number(num2);
alert("Modulus is: "+sum);
}
</script>
<form name="form">
<table>
<tr>
<td>Enter First Number:</td>
<td><input type="text" name="text1"></td>
</tr>
<tr>
<td>Enter Second Number:</td>
<td><input type="text" name="text2"></td>
</tr>
<tr>
<td><input type="button" value="Add" onclick="add();"></td>
<td><input type="button" value="Divide" onclick="divide();"></td>
</tr>
<tr>
<td><input type="button" value="Product" onclick="product();"></td>
<td><input type="button" value="Modulus" onclick="modulus();"></td>
</tr>
</table>
</html>

Output:

On clicking the 'Add' button, result will get displayed:
