Mathematics is the oldest science; it existed in all ancient civilizations: Chinese, Egyptian, Babylonian, Greek. In mathematics, once found regularities are always true: 2+2 was equal to 4 in ancient Greece, it is equal to four now and in centuries to come.

In mathematics, everything that is not necessary to solve a given problem is discarded, and only the most essential is taken into account. Mathematicians deal with abstract concepts. A good example of this is numbers. The number 3 does not mean “3 apples” or “3 pears” but “3 pieces of whatever”. Similarly, a ball in mathematics is not a definite ball, such as a cue ball, but an abstract figure.

He who studies the map of a city is doing mathematics without knowing it. He does not think about houses, cars, pedestrians, and finds the right street, even though the map shows it only as a line.

The task of mathematics, often called the queen of sciences, is not to count but to recognize logical laws. (Being able to count is just a prerequisite for doing mathematics.) The mathematical achievement is not to multiply, for example, 876 by 357, but to prove that there cannot be the largest number because for every number you can create an even larger number by adding 1.

Mathematics is primarily concerned with numbers. But some of its sections had nothing to do with numbers at first. Geometry, for example, studies figures such as a triangle, a circle or a sphere and their properties; probability theory studies random events, such as a six-point roll in a game of dice. But these areas of mathematics are also related to the world of numbers. Thanks to them, for example, we can determine the properties of geometric shapes, such as a straight line or a sphere.
