Marcus wants to use a model to determine the difference -8 -3 (+3). He starts with 8 negative counters.
He wants to add 3 positive counters to the model without changing the value. How can he do that?
A. Add 3 positive counters
B. Add 3 positive counters and take away 3 negative counters
C. Add 3 negative counters
D. Add 3 positive counters and 3 negative counters.
There are a negative counters in a circle for each -.
I think it's D tbh
D looks good to me.

To determine the difference -8 -3 (+3), Marcus wants to add 3 positive counters without changing the value.
To do this, Marcus should choose option B: Add 3 positive counters and take away 3 negative counters.
By adding 3 positive counters, Marcus increases the overall count. However, to keep the value the same, he needs to offset the increase by subtracting 3 negative counters. This way, the total number of counters remains the same, resulting in no change in value.
