How to Use of Arithmetic Operator in JavaScript
In this article I have described about the Arithmetic operator used in JavaScript
JavaScript Operator  Arithmetic Operator
 An operator is used to transform one or more value into a single resultant variable.
 The value to which the operator is applied is referred as operands.
 A combination of an operator and its operand referred as an Expression.
NOTE
 for some operator such as multiplication (*) the order of the operand do not matter. for example A*Y=Y*A true for all integer and floating point number.
 Other operator like String concatenation (+), the order of operand matter. for example "ab" +"cd" not same as "cd" +"ab".
lets take an example
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>JavaScript Oerator</title>
<body>
<p>JavaSript + operator example with variable</p>
<button onclick="myFunction()">CLICK</button>
<p id="demo"></p>
<script type="text/javascript">
function myFunction()
{
txt1 = "welcome to";
txt2 = " MCN IT SOLUTION ";
txt3 = txt1 + txt2;
document.getElementById("demo").innerHTML = txt3;
}
</script>
</body>
</head>
</html>

when we run above program
