Multiplying Integers

Part 1. When integers have the same value (+ or -) the product is positive. (+2)x(+3)=(+6) When the integers have different values (+ or -) the product is negative. (+2)x(-3)=(-6) Part 2. When muliplying integers count the negative signs as odd numbers = negative product and even numbers = positive product. (+2)x(+3)x(-1)=(-6) (+2)x(+3)=(+6) (+6)x(-1)=(-6)

1. 9-1=8 have 9 owe 1 = have 8 +++++++++ - 2. 6+(-7)=13 have 6 remove owe 7 = have 13 ++++++ +++++++ ------- 3. 8-(-2)=10 have 8 remove owe 2 = have 10 ++++++++ ++ -- 4. 10+(-2)=8 have 10 and owe 2 = have 8 ++++++++++ -- 5. 10-4=6 have 10 owe 4 = have 6 ++++++++++ ---- 6. (-8)+(-3)=(-11) owe 8 and owe 3 = owe 11 ----------- 7. 0-5=(-5) have 0 owe 5 = owe 5 ----- 8. 8-4=4 have 8 owe 4 = have 4 ++++++++ ----
