I Can Divide Integers Bell Work: 1. (-2)+(+7)= 2. (-4)+(-5)= 3. (-3)-6= 4. (+5)-(+10)= 5. (-2)(-3)= 6. (+4)(-3)= (+5) (-9) (-5) (+6) (-12)

Wrap up If COLOURS are DIFFERENT (factors oppose) ALWAYS WHITE (Negative) PRODUCTPRODUCT REMEMBER!! Coloured tiles are POSITIVE and White tiles are NEGATIVE REMEMBER!! Coloured tiles are POSITIVE and White tiles are NEGATIVE Hint Algebra-tiles

for Multiplication for Multiplication (+)(+) = + (-)(-) = + ( +)(-) = - (-)(+) = - Rules SYMBOLIC: Same Pos Diff Neg
11
SYMBOLIC: for Division for Division Rules (+) (+) = + (-) (-) = +( +) (-) = -(-) (+) = - Same Pos Diff Neg
