Adding Integers w/ Number Lines

Front

What is the result of adding a positive integer and a negative integer?

Back

The result can be found by subtracting the absolute value of the negative integer from the positive integer. If the positive integer is larger, the result is positive; if the negative integer is larger, the result is negative.

Front

How can you visualize the addition of integers on a number line?

Back

You can visualize it by starting at 0, moving left for negative integers, and moving right for positive integers.
