The result of the division modeled by −108−(−18)−(−18)−(−18)−(−18)−(−18)−(−18)=0 is undefined.
Elaine used the subtraction algorithm to subtract −17−(−3). She got the answer −14, but she does not feel confident that she is correct. Connect the expression −17−(−3) to a two-color counter model. Explain how the two-color counter model can be used to confirm whether Elaine’s answer is correct.(2 points)
In a two-color counter model, we can represent positive numbers using one color (e.g., green) and negative numbers using another color (e.g., red). To connect the expression −17−(−3) to a two-color counter model, we can start by representing −17 using 17 red counters. Then, we can subtract (−3) by removing 3 red counters from the model.
The result should show that Elaine's answer of -14 is correct. If we have 17 red counters representing −17, and we remove 3 red counters representing (−3), we will be left with 14 red counters. This corresponds to the answer −14. By using the two-color counter model, we can visually see that the result matches Elaine's answer, confirming that she is indeed correct.

To solve the equation, we can follow the order of operations (also known as PEMDAS) to simplify the expression step by step.
Step 1: Start by evaluating the division operation.
Dividing two negative numbers will result in a positive value. So, -108 divided by -18 will give us 6.
So now our expression becomes:
6 - (-18) - (-18) - (-18) - (-18) - (-18) - (-18) = 0
Step 2: Simplify the subtraction operations.
When a negative number is subtracted, it is the same as adding its positive value. So, -(-18) is equivalent to +18.
Our expression now becomes:
6 + 18 - 18 - 18 - 18 - 18 - 18 = 0
Step 3: Continue simplifying the expression by performing the remaining subtractions.
6 + 18 - 18 - 18 - 18 - 18 - 18 = -12
However, this result is not equal to 0. Therefore, the given equation −108−(−18)−(−18)−(−18)−(−18)−(−18)−(−18) cannot equal 0.
