The document discusses operations with integers including addition, subtraction, multiplication, and division. It provides rules for each operation such as adding the opposite for subtraction or having an odd number of negatives result in a negative product for multiplication. It also gives examples of simplifying expressions using order of operations with integers. There will be a quiz tomorrow to assess understanding of these integer operations and concepts.

1.  1. Review: Add, Subtract, Multiply Integers
 2. Discuss HW
 3. Dividing Integers
 4. Order of Operations with Integers
 Tiny little quiz tomorrow!

2.  Subtraction:
 Add the
opposite
 Addition:
 Different
signs, subtract
and keep the
sign of the
larger number
 Same signs,
add and keep
the sign

3.  Multiplication:
 Odd number of
negatives, the
product will be
negative
 Even number of
negatives, the
product will be
positive

4.  The rule for dividing
is similar to the rules
for multiplying.
 Same signs = positive
 Different signs =
negative

5.  The population of a small town is changing at
a rate of 255 people per year. How long will it
take for the change in population to be 2,040
people?

8.  Simplify the expression:
 (-4)(-2) – (5)(-3)=
 Step 1: Do the multiplication first
 (-4)(-2) = 8
 (5)(-3)= -15
 Step 2: Follow the rules for subtraction
 8-(-15)= 8+ (+15)= 23

9.  Simplify: 3(5-12)=
 Step 1: Do parentheses first
 (5-12)= 5 + -12= -7
 Step 2: Multiply
 3(-7)= -21

10.  There is extra practice attached to exercises 5
and 6.
 Quiz tomorrow!
