# Negative and Positive Rules

Two Signs Together?

"-" and "+"signs show two things:

1. whether an integer is positive or negative
2. whether the operation is add or subtract

When we do operations (like adding and subtracting) with integers we often end up with two signs next to each other. This can be confusing but the rules below can help:

+3 means positive three. 3 is the same as +3

We usually don't say "positive" or write the + sign so you will not see two plus signs together very often.
