A positive and a positive is equal to a positive. A positive and a negative equals a negative. Likewise, a negative and a positive equals a negative. And two negatives equal a positive.

When the two signs are different, the resultant sign is a negative. However, when the two signs are the same, the resultant sign is a positive. In this case, negative of negative seven is the same as positive seven. The positive numbers are to the right of zero on our number line, whereas the negative numbers are to the left.
