(b) write the answer.
-6 - 2 =

Explanation:

Step1: Represent -6 with chips

We use 6 red negative chips: $(-1)+(-1)+(-1)+(-1)+(-1)+(-1)$

Step2: Subtract 2 (remove 2 positive chips)

Since there are no positive chips, we add 2 zero pairs (2 yellow + chips and 2 red - chips) to the set:
Now we have $(-1)\times8 + (+1)\times2$
Remove 2 positive chips, leaving $(-1)\times8$

Step3: Calculate the total value

$\sum (-1) \text{ eight times} = -8$

Answer:

$-8$
