If m = - 7 and n = 4, what is the value of mn? - 74

-3

-28

-11

When two variables (letters) are beside each other, that tells us that we need to multiply. So if M = - 7 and n = 4, - 7 times 4 = - 28. The reason it is negative is because when you multiply one positive number and one negative number, your answer will always be negative.

-28 all you had to do was multiplie 7 by 4 and get 28 then add the subtraction mark to show it is negative.
