Adding integers with the help of counters makes integer addition very simple. Counters let us visualize the problem expression and then remove zero-sum pairs. We can represent counters in any color. For example, by adding -9 & +4, we can use 9 -ve counters (red) and 4 +ve counters (white). Now, eliminating pairs would have 5 -ve counters as the answer.

Teachers can share these Add Integers with counters Problems to increase students’ grasp of the general rules for adding integers.
