Algebra II/Real Numbers

Real Numbers

Real Numbers are numbers used in your life, such as 2, 4, and including ${\tfrac {6}{8}}$ . Every point on the number line is connected to a real number. All numbers are real numbers.

Rational

Rational Numbers can be represented as "m/n" - m and n being integers and the denominator is not a zero. The decimal of a rational number is either a terminating decimal ( ${\tfrac {6}{8}}$ = .75) or a repeating decimal ( ${\tfrac {8}{6}}$ = 1.6666...). Rational numbers can be normal numbers, such as -3 and 0.

Integers

(-1, -2, -3, -4, -5, -6, -7, -8, -9, -10)

Whole

(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

Natural

(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

Irrational

Irrational Numbers usually consist of decimals that contain a random list of numbers (not terminating/repeating). Example is being pi (π).
