3. Paolo models (-2) x (+3) as shown in the diagram. He determines the correct product, -6. Explain his method works.

      - his method works because even though he didn't remove the zero pairs, the answer will still be -6.

6. Write each expression as a multiplication.

   a)  (+7) + (+7) + (+7)  = (+3) x (-7)

   b)  (-4) + (-4) + (-4) + (-4)  =  (+4) x (-4) 

10. What multiplication statement does each set of diagram represents?

 a)    =   (+2) x (+7)

 

b)    =   (+6) x (-1)
