Mathematics students often encounter confusion when distinguishing between rational and irrational numbers. However, mastering this fundamental concept becomes straightforward once you understand ...

The ancient Greeks wondered when irrational numbers, like pi, can be represented with fractions. Two mathematicians now have a complete answer.

Rational numbers can be expressed as the ratio of two integers, while irrational numbers, such as square roots of non-square numbers, cannot.

Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers. This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as ...

The existence of irrational numbers is best explained with an isosceles right triangle—that is, a triangle with two sides of an equal length that form a right angle.

Three issues are addressed: richness and density of numbers, the fitting of rational and irrational numbers on the real number line, and operations amongst the elements of the two sets. The results ...

Exactly one number plugs the hole between these two sets. Mathematicians give it the label \sqrt {2}. For Dedekind, then, an irrational number is defined by a pair of infinite sets of rational numbers ...
