  1. Positive & NegativeIntegers Destiny S. & Paige H. Mrs. Bius 7th

  2. Adding Rules • Positive + Positive = Positive 5+4=9 • Negative + Negative = Negative (-7) + (-2)= -9 (-7) + 4 = -3 6 + (-9) = -3 (-3) + 7= 4 5 + (-3)= 2 http://www.google.com/url?sa=t&source=web&cd=1&ved=0CBkQFjAA&url=http%3A%2F%2Fwww.basic-mathematics.com%2Fadding-integers-game.html&ei=1bXaTdWSDca1twf2sOnoDg&usg=AFQjCNF9eU4MG-FID4k04TriOvu3RA5TMw

  3. Subtracting Rules • Negative – Positive = Negative (-5) – 3 = - 5 + (-3) = -8 • Positive – Negative = Positive + Positive = Positive: 5 – (-3) = 5 + 3 = 8 • Negative – Negative = Negative + positive = Use the sign of the larger number and subtract (change double negatives to a positive) (-5) – (-3) = (-5) + 3 = -2 (-3) – (-5) = (-3) + 5 = 2 http://www.google.com/url?sa=t&source=web&cd=2&sqi=2&ved=0CCcQFjAB&url=http%3A%2F%2Fwww.basic-mathematics.com%2Fsubtracting-integers-game.html&ei=LbbaTbaMO4eitgf109DoDg&usg=AFQjCNHGQNZSa3Bu8vC95I_AgBsDW2uT8g

  4. Multiplying Rules • Positive x Positive = Positive; 3 x 2 = 6 • Negative x Negative = Positive; (-2) x (-8) = 16 • Negative x Positive = Negative; (-3) x 4 = -12 • Positive x Negative = Negative; 3 x (-4) = -12 http://www.google.com/url?sa=t&source=web&cd=5&sqi=2&ved=0CDwQFjAE&url=http%3A%2F%2Fwww.basic-mathematics.com%2Fmultiplying-integers-game.html&ei=ZbbaTeD0NMyUtwf01O3oDg&usg=AFQjCNHFvIuiDPc916KV9kjZ8-pB7s9GcA

  5. Dividing Rules • Positive / Positive = Positive; 12 / 3 = 4 • Negative / Negative = Positive; (-12) / (-3) = 4 • Negative / Positive = Negative; (-12) / 3 = -4 • Positive / Negative = Negative; 12 / (-3 = -4 http://www.google.com/url?sa=t&source=web&cd=2&sqi=2&ved=0CCAQFjAB&url=http%3A%2F%2Fwww.math-play.com%2FIntegers-Jeopardy%2FIntegers-Jeopardy.html&ei=27baTfHqDIK5twecmvHoDg&usg=AFQjCNHU1BCS7snNGNDr4tC6ofa-hqM_oQ
