Question

Why can we model -4×3 by jumping three units to the right four times and then jumping from 12 to -12

Answer 1

Subtracting 3 steps from 4 times jumping three units to the right can be modeled by jumping from 12 to -12.

Step-by-step explanation:

When subtracting 3 steps from 4 times jumping three units to the right, you can think of it as adding 3 steps in the opposite direction.

So, if you jump three units to the right four times, you would end up at 12. Then, adding 3 steps in the opposite direction would bring you back from 12 to -12.

Therefore, modeling -4×3 by jumping three units to the right four times and then jumping from 12 to -12 is a way to visualize the subtraction of 3 steps.
