A.
For multiplication: If the signs are the same the result is positive. If the signs are different the result is negative.
[tex]\begin{gathered} -\times-=+ \\ +\times+=+ \\ -\times+=- \\ +\times-=- \end{gathered}[/tex]Therefore, the greatest product will be given by:
[tex]-3\times-2=6[/tex]B.
The least of the products is:
[tex]-3\times3=-9[/tex]C.
Changing the order of factors does not change the product.
Therefore:
[tex]-3(-2)=-2(-3)=6[/tex]
