We will be having a quiz on these types of problems on Tuesday Dec. 16th.

Simplifying Equations

Toady in Math we worked on Simplifying equations. When simplifying what we
are trying to do is put all like terms together. an example of a like
term, is a number or a variable at the same exponent level. For example 3x
and 6x are both groups of x at the same exponent level.

Visit the following website to review how to simplify equations.

A quick reminder that we will be having an Entrance Quiz on what we have
learned about One Step, Two Step and Multi-step Equations on Wednesday
November 18th.

Math - Order of Operations

Complete pages 3-6 of the following BEDMAS [

]Booklet.

Integers

Rules for integers.

Adding: If the signs are the same, add them and put down the sign.

ex. -6 + -5 = -11

Adding if the signs are different, find the difference by subtracting
the smaller number from the bigger number, then write down the
sign of the bigger number.

ex. -12 + 7 =  12 - 7 = 5 put down the sign of the bigger number, so
it should be -5

Subtraction: Change the subtract sign to Add, and change the sign
of the 2nd number, then follow Addition rules.

ex. 7-(-9)= 7+(+9)= +16

For Multiply and Divide

All you have to remember is that if the Signs are the same,
the answer is Positive, and if the sings are different,
the answer is Negative.

ex. -6 x -7 = +42
