Yes, integers can have both positive (+) and negative (-) signs. Integers are whole numbers that can be either positive, negative, or zero. The positive sign indicates a number that is greater than zero, while the negative sign indicates a number that is less than zero. For example, +5 and -5 are both integers, where +5 is a positive integer and -5 is a negative integer.
