How use arithmetic operator in JavaScript with in HTML programs
In the JavaScript arithmetic operators are used to calculate a variable value
Within JavaScript tag.when JavaScript file write separately and save with extension .js
then add it in html program by lik tag as like
<link rel="javascript" type="text/javascript" href="tpe full with name and extension of javascript file/>
Or you can use JavaScript tag with html file under the header tags
here we give some example to using arithmetic operators for arithmetic operations
Example 1
Open note pad and type fallowing code save with .HTML extension and open with any web browser.
Look JavaScript code
<Script>
var number1=10;
var number2=20;
var sum=number1+number2;
var mul=number1*number2
var sub=number1-number2;
var div=number1/number2;
var mod=number1/number1;
document.write("sum fo two number="+sum );
document.write("</br>Multiplication of two number="+mul);
document.write("</br>Division of two number="+div);
document.write("</br>Substraction of two number="+sub);
document.write("</br>Mode of two number="+mod);
</Script>
output look like this
sum fo two number=30
Multiplication of two number=200
Division of two number=0.5
Substraction of two number=-10
Mode of two number=1
Example 2
Open note pad and type fallowing code save with .HTML extension and open with any web browser.
<html>
<head>
<title>arithmetic operations.</title>
<Script type="text/javascript">
function makeresult()
{
var number1=Number(document.getElementById("one").value);
var number2=Number(document.getElementById("two").value);
var sum=number1+number2;
var mul=number1*number2;
var sub=number1-number2;
var div=number1/number2;
var mod=number1/number2;
document.getElementById("summ").value=sum;
document.getElementById("mull").value=mul;
document.getElementById("divv").value=sub;
document.getElementById("subb").value=div;
document.getElementById("modd").value=div;
}
</Script>
</head>
<body bgcolor="green">
<center>
<table border="5" bgcolor="yellow">
<form method="GET" action="index.html">
<tr><td colspan="2" align="center" >Arithmetic operations.</td></tr>
<tr><td>Enter the frist Number</td><td><input type="text" id="one" name="one"/></td></tr>

<tr><td align="right">Result:</td><td><input type="text" id="divv" name="divv"/></td></tr>
<tr><td align="right">Result:</td><td><input type="text" id="modd" name="modd"/></td></tr>
<tr><td align="center" colspan="2" align="center"><input type="button" value="calculate" onclick="makeresult()"/></td></tr>
</form>
