Integer Programming 9 The linear-programming models that have been discussed thus far all have been continuous‚ in the sense that decision variables are allowed to be fractional. Often this is a realistic assumption. For instance‚ we might 3 easily produce 102 4 gallons of a divisible good such as wine. It also might be reasonable to accept a solution 1 giving an hourly production of automobiles at 58 2 if the model were based upon average hourly production‚ and the production had the interpretation

Addition and Subtraction of Integers Addition of Positive Integers Consider the addition of 2 + 3. The plus sign‚ +‚ tells us to face the positive direction. So‚ to evaluate 2 + 3‚ start at 2‚ face the positive direction and move 3 units forwards. This suggests that: Positive integers can be added like natural numbers. Addition of Negative Integers Consider the addition of (–2) + (–3). The plus sign‚ +‚ tells us to face the positive direction. So‚ to evaluate
