[tex]\boxed{21}[/tex]

When you multiply a negative and a negative, it is going to be a positive number. In this case, we're multiplying -3 and -7, which is equal to 21. If you're not sure of the answer for multiplication problems like this, just use a calculator to check your work.

Answer: [tex]\boxed{21}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When you multiply two negatives (-, -,), you are gonna get a positive(+)

[Like making a cross out of two lines].

[tex]-3(-7) = +3(+7)[/tex]

Since 3(7) normally equals 21, that would be the answer for this case.
