To represent the expression \(-2 \cdot -6\), we can use a model that illustrates the multiplication of two negative numbers. One common way to represent this concept is through the following equation:
\[
- (-2) \cdot (-6) = - ( + ) \]
In this model, the first negative number can be seen as taking away or reversing the sign of a positive value, while the second negative number also represents a reversal. Thus, the product of two negative numbers results in a positive value.
So the answer would be represented as:
\[
- (-2) \cdot (-6) = + 12 \]
This implies that the multiplication of two negatives yields a positive. In numerical value, \(-2 \cdot -6 = 12\).
