Predict the product of -4 x -1.   Explain your answer.  [we do not know how to "explain" it's 4.]

Thank you for the opportunity to help you with your question!

(-4) *(-1) = 4

when ever two minus (-) sign multiplies it becomes +

and remain 4  *1 = 4

hence answer is +4   or we can simply write  4

We are presented with this question in the context of "number lines" and "chip boards".  I think we are expected to use those terms in the answer.

This doesn't help.  We have to "explain" (in a word sentence) how we predicted the answer.  Thanks, anyway.
