The expression −3⋅8 represents the multiplication of -3 and 8, which can be visualized using a model. In this case, the correct representation would be:
**−8 + −8 + −8**
This indicates that you are taking three groups of -8, which effectively models the expression -3 multiplied by 8. Each -8 represents a negative quantity, and by adding three of them together, you accurately represent -3 * 8.
**−8 + −8 + −8**
