Work Step by Step
(a) In this problem, we see that there is one negative sign in between two numbers, so we see that this negative sign is indicating subtraction.
(b) In this problem, we see a negative in front of a single number. Thus, this is indicating that the number is negative.
(c) In this case, we see two negative signs in front of a single number, so we know that this indicates that the number is positive since a negative times a negative is a positive.
