The 4 numbers that are multiplied together have to be negative, right? Because negative divided by negative is positive.

So, now focus on the 4 numbers that are multiplied together. These 4 numbers are the factors they're talking about.

Think about the signs those 4 blanks have to have.

"Jenna multiplied four numbers together and then divided by -2. The result was a positive value."
That means:

@BangkokGarrett no need to get mad:) Its all good...

Answer 28

@samtab start writing down and multiplying negatives and seeing what you get...eg \[\Large (-1)(-1)(-1)(-1) = 1\] \[\Large (-1)(-1)(-1)(1) = -1\]

you will have to actually try this yourself, though.
