The ancient Greeks introduced names, concepts and self-thinking into mathematics, and they began to guess how mathematics came into being very early. Although their guesses were just jotted down, they almost occupied the thinking field of guesses first. What the ancient Greeks wrote down at random became a lot of articles in the19th century, but it became an annoying cliche in the 20th century. Herodotus (484-425 BC) was the first person who began to guess. He only talks about geometry. He may not be familiar with general mathematical concepts, but he is sensitive to the exact meaning of land survey. As an anthropologist and social historian, Herodotus pointed out that the geometry of ancient Greece came from ancient Egypt. In ancient Egypt, because the land was flooded every year, people often needed to re-measure the land in order to achieve the purpose of taxation. He also said: The Greeks learned the use of the sundial from the Babylonians and divided the day into 12 hours. Herodotus' discovery was affirmed and praised. It is superficial to speculate that ordinary geometry has a glorious beginning.

The word "mathematics" comes from Greek, which means something "learned or understood" or "acquired knowledge", and even has the meanings of "obtainable things" and "learnable things", that is, "knowledge gained through learning". The meanings of these mathematical names seem to be the same as those of Sanskrit cognates.

Use:

We need mathematics to solve difficult problems in science.

We need mathematics to find new ways to overcome intractable diseases, new ideas to design industrial machines and small inventions to save family labor.

We also need mathematics more and more to acquire common things in our daily life.
