This is helpful information that can be used all year by my students!


           Order of Operations:

   G                              1) Parenthesis or other grouping symbols

   E                              2) Exponents

  MD-left to right          3) Multiplication or division in the order it appears from left to right

  AS-left to right           4) Addition or subtraction in the order it appears from left to right


        Adding and Subtracting Rational Numbers:                               

               ______________________________                   

               Same sign, add the numbers,                                -2 - 6 = -8        4 + 5 = 9          

               Different signs, subtract.                                                             

               Take the sign of the dominant number,                   2 - 6 = -4       -4 + 5= 1            

               Then you'll be exact.

                ______________________________                     

                A line and a line                         -8 – - 10

                Make a plus sign                        -8 + 10    

                                                                        2

       Multiplying and Dividing Rational Numbers

               _______________________________

               pos x pos = pos                      6 x 8  =  48

               pos x neg = neg                       6 x -8 = -48   and   -6 x 8 = -48

               neg x neg = pos                      -6 x -8 =  48

               any number x zero = zero       -6 x 0  =  0

               pos / pos = pos                                                           10/2  =  5

               pos / neg = neg  (Also, neg / pos = neg)                     10/-2 = -5    and   -10/2 = -5

               neg / neg = pos                                                          -10/-2 = 5

               zero / any number = zero                                            0/7 = 0              0/-4 = 0

               any number / zero = there is no answer for this!        7/0 = undefined

 ___________________________________________________________________

                    Multiplying Fractions

            Write problems side by side.

            Write fractions in improper form.

            You DO NOT get common deminators.

            Cancel any common factors in the numerators 

            and denominators.

            Before you leave your answer make sure it is

            in simpliest form.           

      _______________________________________

                    Dividing Fractions  (KCF - Keep Change Flip)

            Dividing fractions, don't ask why

            Just flip the second number and multiply.

            And before you say goodbye,

            Don't forget to simplify.

      _______________________________________

                     Adding and Subtracting Fractions

           Write the problem verically (up and down)

           Get common denominators.

           Put dominant number on top.

           You do not have to change to improper fractions.

           With subtraction you may have to borrow.

           Simplify your answer.
