start with 6 positive counters.

then add 3 negative counters.

add.

\\(6 + (-3) = \square\\)

Explanation:

Identify the zero pairs

$$ 3 \text{ positive counters} + 3 \text{ negative counters} = 0 $$

Count the remaining counters

$$ 6 - 3 = 3 \text{ positive counters} $$

State the final sum

$$ 6 + (-3) = 3 $$
