Rational Numbers
- Rational numbers are defined as numbers that can be expressed in the form of a fraction a/b, where 'a' and 'b' are integers and 'b' is not zero.
- The term "rational" comes from the word "ratio."
- The symbol "Q" for rational numbers was introduced by the mathematician Giuseppe Peano in the late 19th century.
Irrational Numbers
- Irrational numbers are numbers that cannot be expressed as a simple fraction. They have non-repeating and non-terminating decimal expansions.
- The concept of irrational numbers dates back to ancient Greece, specifically to the discovery of the square root of 2 by the Pythagoreans.
- The symbol "R" for real numbers, which includes both rational and irrational numbers, was popularized by mathematicians in the 19th century.
Real Numbers
- Real numbers encompass all rational and irrational numbers, representing all possible values along the number line.
- The formal development of real numbers was significantly advanced by mathematicians such as Georg Cantor and Richard Dedekind in the late 19th century.
Fractional Numbers
- Fractional numbers are essentially a subset of rational numbers, represented as a/b.
- The concept of fractions has been known since ancient times, with early uses in Egyptian mathematics around 2000 BCE.
- While no single inventor can be credited with fractions, they have evolved through various cultures over centuries.
In summary, rational numbers were denoted as "Q" by Giuseppe Peano, while irrational numbers were recognized by the Pythagoreans. The formalization of real numbers was advanced by Cantor and Dedekind, and fractional numbers have existed since ancient civilizations.
