Integers & Absolute Value Integers & Absolute Value • The absolute value of a number is the distance the number is from zero on the number line. • Distance is always positive. Think of it like driving in a car. You can go North, South, East or West, but you can not go negative miles. Integers & Absolute Value -4 -3 -2 -1 0 1 2 3 Absolute value is symbolized using two bars like this: 4 4 4 -9 9 4 4 2 2 Examples Ex #1 -6 2 62 4 Ex #2 5 4 5 4 20 Examples Ex #3 -6 6 Ex #4 - - 12 12 Thermometers are oftengain, used to Words like: below, loss, Words like: above, explain positive and negative increase or deposit mean decrease or withdraw numbers. mean negative integers positive integers. Thermometers are often used to explain positive and negative numbers. Words like: above, gain, increase or deposit mean positive integers. Words like: below, loss, decrease or withdraw mean negative integers Opposites • In integers opposites add up to zero. • +25 + -25 = 0 • -7 + 7 = 0 • 101 + -101 = 0 BACK If an Integer has no sign, it is a positive number.
