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

______________________________

Same sign, add and keep                                      -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.

______________________________

Add a line and                           -8 – - 10

change the sign                         -8 + 10

OR subtracting is the                     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.

in simpliest form.

_______________________________________

Dividing Fractions  (KCF - Keep Change Flip)

Just flip the second number and multiply.

And before you say goodbye,

Don't forget to simplify.
