Techniques to Simplify Algebraic Expression

Introduction

When it comes to simplifying algebraic expressions, it's really easy...as long as use this amazing method of P.E.M.D.A.S:
P: parenthesis
E: exponents
M: multiplication
D: division
A: addition
S: subtraction

NOTE: FOR MULTIPLICATION AND DIVISION, IT IS LEFT TO RIGHT AND SAME GOES FOR ADDITION AND SUBTRACTION

P.E.M.D.A.S is probably the only technique you'll need to apply when simplifying because it is a great combination of all the basic operations you use in math. With P.E.M.D.A.S, algebra is as easy as ABC's!

Let's Give It a Try!

Now that we know our main ingredient to algebra, let's get cooking!

Let's say that you have a problem such as:

(24x37) - 43x6

Remember to use PEMDAS:

First, we solve the parenthesis (24x37) which equals 888.

Now we have 888-43x6.

Next, we will do multiplication or division (left to right) since there are no exponents in this case.
There isn't any division either, so just simply multiply.

So, that means we'll do 43x6 which equals 258.

Therefore we now have 888-258 which will give us a difference of  630. So, our answer is 630. Even though our problem is solved, we still need to put this in a more clear format, like this:

(24*37)-43*6
888-43*6
888-258
=630

By writing out our problem like this, it is easy to understand how the problem is solved.

Now that we've understood the concept of simplifying algebraic expressions, you can try some of these by yourself!
