A. Fraction
B. Negative Number
C. Decimal or Percent
D. Postive Number
E. Both B and D
Interger is E, a Negative or Postive Whole Number
2. When Adding, Subtracting, or multiplying an Integer, you always get an Integer as an answer

A. True
B. False
• A. True.  When Adding, subtracting or multiplying an Integer, you ALWAYS get an integer as the answer.
• -3*11= -33
• -3 + 4= +1 or 1
• Remember an Integer is a Postive or Negative WHOLE number (not a fraction or percent, or decimal).
3. When dividing an Integer, you always get an Integer as the answer.

A. True
B. False
• B. False.  It is possible to get a fraction, or decimal when dividing with a integer.
• 8/5 (8 divided by 5) = 1.6
4. Example Card:

When adding and subtracting with Negative Integers, imagine a line that moves left and right, with 0 as the center, negative numbers to the left of zero, positive numbers to the right of zero.
• ____________________0_______________________
• -10   -5  -4  -3  -2  -1             1  2  3  4  5      10        20

• Adding a postive number moves to the right
• -3 plus 4 equals positive 1
5.     Example Card
Adding a positive number to a negative integer moves the number to the right.
-3 plus 6 equals postive 3 (-3+6=3)
-10 plus 5 equals negative 5 (-10+5= -5)
• ____________________0______________________
• _-10   -5  -4  -3  -2  -1             1  2  3  4  5      10        20

-3 plus postive 6, move 6 sports to the right, to positive 3.

-10 plus positive 5, move 5 spots to the right, to negative 5.
6.   Example Card
Subtracting a postive number moves to the left.
4 minus 3 equals 1 (4-3=1)
-3 minus 5 equals negative 8 (-3 - 5= -8)
3 minus 5 equals negative 2
• __________________ 0________________
• -10 -9 -8-7-6-5-4-3-2-1  1 2 3 4 5 6 7 8 9 10

• 4 minus 3 (postive 4, move left 3 spaces, to postive 1)
• -3 minus 5 (negative 3, move 5 spaces left, to negative 8)
• 3 minus 5 (postive 3, moves 5 spaces left, to negative 2)
7. Example Card
When adding a Negative number, move left:
Postive 4 plus Negative 3 equals postive 1.
4 + -3= 1
Negative 3 plus Negative 2 equals Negative 5.
-3 + -2= -5.
• ______________________0_______________________
• -10-9-8-7-6  -5  -4 -3 -2  -1    1  2  3  4  5  6  7  8  9  10

• 4 + -3 (Postive 4, move left 3 spaces to postive 1)
• -3 + -2 (Negative 3, move left 2 spaces to Negative 5).
8.  Example Card
When subtracting a Negative Number, move right:
Positive 1 minus Negative 2 equals postive 3
1 - -2= 3 (subtracting a negative is like addition)
Negative 2 minus Negative 3 equals 1
-2 minus -3= 1
• ____________________0_____________________
• -10 -9 -8-7-6 -5 -4 -3-2-1   1 2 3 4 5 6 7 8 9 10
• 1- -2 (postive 1, move right 2 spaces, to postive 3)

-2 - -3 (negative 2, move right 2 spaces to postive 1)
9. Multiply and Divide Integers:
Step 1: Ignore Signs and do the problem
Step 2:  A. If original signs match, the result in postive
3*10=30, -5*-3=15, 24/8=3, -24/-8=3
B. If original signs don't match, the result is negative.
3*-10= -30, -5*-3= -15, -24/8=-3
