Could someone please explain this to me: Use counters to model the sum: 8 + ( -3 ). How I solved this was : 8 - 3 =5.

Use 8 counters (objects) and take 3 away.
So I could say: Start with 8 marble counters and take away 3 marble counters. There should be 5 marble counters left. Is this how I should explain this question: Use counters to model the sum: 8+(-3.
Yes. That looks good.
