What is the sum of a negative integer and a positive integer?

How do you visualize combining integers using counters?

• Use red counters for negative integers and yellow counters for positive integers; combine them to see the result.

• Use blue counters for both positive and negative integers; they cancel each other out.

• Use green counters for positive integers and no counters for negative integers; only positive integers are counted.

• Use yellow counters for negative integers and red counters for positive integers; they do not combine.
