for the 1st 9 Weeks in 6th, 7th and 8th Grades (UL and Algebra I too)!!!! Junior High Math Assignments

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 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

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.
