7th Grade - Integers and PEMDAS

Rules of multiplications and division of integers:

+ +  =  +

-  -   =  +

+ -   =  -

-  +  =  -

Today we discussed order of operations.  Just like there is an order to what you do in the morning, there is an order to what operations we do first in mathematics.  Recall our work on PEMDAS.

Homework: Exercise 2.4 (page 50) # 1 (all), #2 (a-e)
