Multiplying and Dividing Integers 4 X 5 = 20 or (+4)(+5) = +20 and (-4)(-5) = +20 +18/+6 = +3 -12/-4=+3 How about (+4)(+2) = +15/+3 = (-6)(–5) = Can we see a pattern here? Is there a rule for multiplying/dividing integers when the signs are the same? What about: (+8)(–2)= (-7)(+2)= +12/–4= Can we see a pattern here? What is the rule for multiplying/dividing integers when the signs are the same?

Multiplying and Dividing Integers Solve: (-7)(+4) = (-5)(–3)= (+24)/(–6) = (+9)/(–3) = (-12)/(+6) = (-4)(+9) =
