Answer:
The product of (-4)(7) is -28
Step-by-step explanation:
First you will multiply the number together.
This gets you -28.
The reason it is a negative number is because when you multiply a positive and a negative number together, you get a negative number. 
Whereas, if it were two negative numbers, (-4)(-7), or two positive numbers, 
(4)(7), the answer would have been positive, 28.
