Show More to mark with or distinguish by numbers: To have as a total; amount to a number: Nonetheless tallying systems are considered the first kind of abstract numeral system. The story goes that Hippasus discovered irrational numbers when trying to represent the square root of 2 as a fraction.
The search for roots of quintic and higher degree equations was an important development, the Abel—Ruffini theorem RuffiniAbel showed that they could not be solved by radicals formulas involving only arithmetical operations and roots. Calculus actually solves the problem.
Babylonian and Egyptian texts used it. A "set" is a term like the term "point" is in Geometry where it is not defined but taken as a "primitive" whose meaning is brought out by the axioms. Cantor applied the notion of the correspondence to infinite sets such as the sets of integers, rational, irrational or real numbers.
As I already mentioned, it takes methods beyond Arithmetic to introduce irrational numbers. In unison as numbers are called out by a leader: To total in number or amount; add up to: Is it what you mean?
It is interesting to observe the characteristic unity of Mathematics as reflected in this example. As a collective noun number may take either a singular or a plural verb.
