Use colored counters to answer the question. Typically, black counters represent a profit or a positive number, while red counters represent a loss or a negative number. Here, use white in place of red, that is, consider a white counter to mean what a red counter would in the typical case.What colored counters would have to be added to this array in order to represent -5?
Fill in the blank(s) with the appropriate word(s).
1 white counter
