Which expression is represented by the diagram? ( Marked 1-4, I can't paste the question.)
wel

Answer:

-6-(-1)

Step-by-step explanation:

Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6.  Then since the last box is being taken away, we are subtracting it.  The last box is still negative though so the last part is -1.  Since -6 subtracted by -1 is -6-(-1), the answer is:

-6-(-1)
