### Weeks idol powerpoint

1. 1. IDOL Project by Ronald Weeks
2. 2. Math Objective The student will be able to: Describe and classify Types of Numbers in the Real Number System
3. 3. Real Numbers The Real Number System consists of both Rational and Irrational Numbers. These numbers can be pictured as points on a Real Number Line:
4. 4. Rational Numbers Natural Numbers – set of counting numbers {1, 2, 3, 4, 5, 6, ...} Whole Numbers – set of natural numbers that include the number ‘0” {0, 1, 2, 3, 4, 5, 6, …} Integers – set of whole numbers and their opposites {…,-3, -2, -1, 0, 1, 2, 3, …}
5. 5. Definition Rational Numbers are any numbers that can be expressed in the form of a/b, where a and b are integers and b ≠ 0. For example, integers can be written with a denominator of 1 {…, -3/1, -2/1, -1/1, 0/1, 1/1, 2/1, 3/1, …} Rational numbers can also be expressed by using terminating decimals or repeating decimals.
6. 6. Terminating decimals are decimals that contain a finite number of digits. For example: 0.75, 2.5, -10.25, -0.5, … Note: The example terminating decimals respond to the fractions 3/4, 2½, -10¼, -½ Repeating decimals are decimals that contain an infinite number of digits. For example: 0.333…, -2.666…, 0.8181 Note: The example repeating decimals respond to the fractions 1/3, -2 2/3, 9/11
7. 7. Irrational Numbers An Irrational Number is a number that cannot be written as a fraction and the decimal equivalent does not terminate nor repeat. For example: Π (Pi) is an irrational number. The value of Π is: 3.1415926535897932384626433832795… Radical numbers that cannot simplify to a rational number are irrational: √2 ≈ 1.414213562373095… ³√7 ≈ 1.912931182772389…
