Arithmetic Operations
A typical arithmetic operation operates on two numbers.
The two numbers can be literals or Variables
The addition operator (+) adds numbers:
Example
<script>
var x,y,z; ⁄ ⁄declare vaariables
x=5;
y=10;
z=x+y;
document·write("Addition of "+ x +"+"+ y+"="+z+"<br/>");
</script>
var x,y,z; ⁄ ⁄declare vaariables
x=5;
y=10;
z=x+y;
document·write("Addition of "+ x +"+"+ y+"="+z+"<br/>");
</script>
Note:
Using "+" we can concate string in Javascript;
The subtraction operator (-) subtracts numbers.
Example
<script>
var x,y,z; ⁄ ⁄declare vaariables
x=10;
y=5;
z=x-sy;
document·write("Addition of "+ x +"-"+ y+"="+z+"<br/>");
</script>
var x,y,z; ⁄ ⁄declare vaariables
x=10;
y=5;
z=x-sy;
document·write("Addition of "+ x +"-"+ y+"="+z+"<br/>");
</script>
Note:
Like above example we can perform all Arithmetic Operations
