Two irrational numbers whose sum is rational

We check if it is rational or irrational. Let us assume that is a rational number.

Again, by definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator denominator not zero. So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form. Remember that integers are closed under multiplication, i. Thus, multiplying two rational numbers produces another rational number. Look out! This next part gets tricky!! The sum of two irrational numbers, in some cases, will be irrational.

The Pythagoreans were a philosophical sect in ancient Greece. Their philosophy included reincarnation and purifying the mind through the study and contemplation of mathematics and science. One of their principles was the cosmos is ruled by order, specifically mathematics and music. They even held mystic beliefs about specific numbers and figures. For example, the number 1 was associated with the mind and essence. Four represented justice, as it is the first product of two even numbers. Most famously, though, is the association with the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the shorter sides of the triangle the legs equals the square of the longer side the hypotenuse. Even the ancient Egyptians used this relationship, as triangles with side measures 3, 4, and 5 were often used in surveying following the flooding of the Nile. There is a story of a Pythagorean, Hippasus, discovering that not all numbers could be expressed as fractions.
