Multiplying/Dividing Integers

I can multiply and divide integers.

Same rules apply for both multiplication and division.

positive x/ $\div$  positive = positive 

negative x/ $\div$  negative = positive

positive x/ $\div$  negative = negative

 $\left(-3\right)\left(8\right)=-24$  , negative x positive = negative

 $\left(-11\right)\left(-11\right)=121$  , negative x negative = positive

 $\left(-81\right)\div9=\left(-9\right)$  

negative divided by positive = negative

 $\frac{-36}{-6}=6$  

negative by negative = positive

 $-\frac{21}{7}$  

 $\frac{-21}{7}\ or\ \frac{21}{-7}\ \ \ or\ -1\left(\frac{21}{7}\right)$  

If a fraction is negative, that means either the numerator OR denominator is negative, not both

 $\frac{-21}{-7}=\frac{21}{7}$  

Negative divided by negative = positive
