How to use Math and Assign operator with variables in JavaScript tutorial for beginners.

SUBSCRIBE

In this tutorial we are going to learn about math and assignment operators in JavaScript. In the course of learning, we will create some variables with some numbers stored into it and then we will see the effects using math operator such as addition, subtraction, multiplication and division. These are the math operators used in JavaScript along with the usage of modulus operator; an operator to show the remain after a division is carried out.
On the other hand we are going to learn about assignment operator. This is a crucial information that will eventually come handy for beginners. In the previous cases suppose we want to increase or decrease the value of a particular variable by one value. So far the knowledge that we have gathered would allow us to do this:

var a = a + 1; or
var a = a - 1;

But using the assignment operator, we will be able to shorten the above syntax. This may be advantageous as in conditional statements, such as in an if-else block statement,
or in loops we will get some advantages in building up the conditions. Using assignment operators we can increase the value of a particular variable to any number, or subtract it,
or multiply it, or divide it. This is what we are going to learn in this tutorial, how to make use of the most of it.
