Question

Use counters subtract -1 - 2

Answer 1

To subtract -1 and -2 using counters, you can imagine starting with a counter at 0 and then moving it backward by -1 and -2 steps:

Counter starts at 0.

1. Subtract -1: Counter becomes 1.

2. Subtract -2: Counter becomes 3.

So, the result of subtracting -1 and -2 using counters is 3.
