POSITIVE AND NEGATIVE INTEGERS What Are Positive and Negative Integers? • Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5. • Negative integers are all the opposites of these whole numbers, numbers that are less than zero: -1, -2, -3, -4, -5. • Zero is considered neither positive nor negative. How to add with positive and negative integers: • If one of the integers is negative, subtract the absolute value of it from the other number. Example: 14 + (-6) = 14 - 6 = 8 • If both of the integers are negative, add their absolute values and prefix the number with a negative sign. Example: -8 + (-2) = -10 How to subtract with positive and negative integers: To subtract integers, change the sign on the integer that is to be subtracted. • If both signs are positive, the answer will be positive. Example: 14 - (-6) = 14 + 6 = 20 • If both signs are negative, the answer will be negative. Example: -14 - (+6) = -14 - 6 = -20 • If the signs are different subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value. Example: 14 - (+6) = 14 - 6 = 8 Example: -14 - (-6) = -14 + 6 = -8 © Copyright NewPath Learning. All Rights Reserved.
