The addition sentence modeled is:
[tex](-4)+(-4)+(-4)=-12[/tex]
In the number line you can see the three segments of four units one after another.
The multiplication sentence is:
[tex]3\cdot(-4)=-12[/tex]
In the picture there are 3 segments of 4 units each one, the negative sign indicates the direction, to the left in this case.
Finally, we can see a division sentence in the number line:
[tex]\frac{(-12)}{(-4)}=3[/tex]
In the picture we can see that the lenght of all segments together is (-12) and there are 3 segments of length (-4) that enter into the (-12).
