Arithmetic operators

In JavaScript, like other programming languages, we can do some arithmetic operations. In your school, you might have already learned how to add two numbers, subtract one number from another number, multiply two numbers, and divide a number with another. You can do all these things in JavaScript with the help of a few lines of code.

In JavaScript, we use the following arithmetic symbols for the operations:

Operator	Description
+	To add
-	To subtract
*	To multiply
/	To divide
%	To find the reminder (called modulus operator)

Addition

Suppose you have two variables, x and y, with the values 3 and 4, respectively. What should we do on the console to store the values on the variables?

Yes, we do the following:

var x = 3; // 3 is stored on variable x
var y = 4; // 4 is stored on variable y

Then, press Enter.

Take another variable that will hold the summation of x and y, as follows:

var z = x+y; // This syntax stores the sum of x and y on z

Can you tell me what will happen...
