Order of Operations




We use BDMAS because all of the different countries in the world
must have a standardized system for completing large equations.

                      BDMAS stands for:
                         Brackets

                          Division

                       Multiplication

                         Addition

                        Subtraction
Brackets



The first step in BDMAS are Brackets. Brackets in math look
like this (). They go around a single equation or multiple
equations. The reason of brackets are to change the answer.
They work because when you put them around an equation it
will change when it is answered so it will affect the other
equations.
ex.

                     
2+3x4=14             (2+3)x4=20
No brackets.         With brackets.
Multiplication/Division


The second step in BDMAS is multiplication and division. To tell
which operation (x or 歎) you do first is to look and see which
one is in front of the others and that equation is what you do.
We do multiplication and division as you would normally on a
single equation. They look like this x 歎.
ex.
                            
6x4歎4=6                   6x4歎2=12
Addition/subtraction

The third step in BDMAS is addition and subtraction. To tell
which operation (+ or -) you do first is to look and see which one
is in front of the others and that equation is what you do. We do
addition and subtraction as you would normally on a single
equation. They look like this + -.
ex.
                                 
10-6+3=7                      10-6+3=1
Examples of BDMAS

      BDMAS


   8歎2x6-7+8=25
    9-8+7x6歎7=7
   5-3+9歎3x4=14
