BEDMAS


 * B**rackets
 * E**xponents
 * D**ivision
 * M**ultiplication
 * A**ddition
 * S**ubtraction

Remember that in an equation, division and multiplication have the same weight. Similarly addition and subtraction have the same weight so always performs these functions from left to right.For example, 2+3-4x6 =2+3-24 =5-24 =--19

-/- = + +/+ = + -/+ = - +/- = -

We have to very careful when we perform BEDMAS for it can become very confusing. Lets take a simple equation. For Example: 4+5x6

Firstly lets fix this question by placing brackets to make this problem seem simpler and confuse ourselves 4+(5x6)

As stated in BEDMAS we have to solve this problem by first doing the brackets 4+(5x6) =4+(30)

Now, as you see, answering this problem has obviously become easier Therefore... 4+(5x6) =4+(30) =34

Keeping this concept in mind we can then be able to solve more difficult equations For Example: (x=3, y=2, z=4)

5x-[4y-{7x-(3z-2y)+4z-3(x+3y-2z)}]

=5(3)-[4(2)-{7(4)-(2(3)-2(2))+4(4)-3(3+3(2)-2(4))}] =5(3)-[4(2)-{7(4)-(2)+4(4)-3(1)}] =5(3)-[4(2)-{28-(2)+16-3}] =5(3)-[4(2)-26+13] =5(3)-[8-26+13] =5(3)-(-5) =15-(-5) =15+5 =20

The point of this page is to notify you that by adding little things like adding brackets, expanding exponents and other tricks ,you are able to make the problems seem easier,more clear and therefore more simplier for you to solve.

Using BEDMAS, you are then able to solve longer and more difficult equations. Please feel free to pose any questions.
