In terms of the number of merchants, thousands are usually represented by K, but recently there have been many M's, such as 1. 1M is 1 ten thousand, which means 1000000.

Counting units shall include integer parts and decimal parts, arranged in the following order: Beijing, Gigabit, Hundred megabytes, Ten megabytes, Trillion, Billion, Billion, Million, Hundred Thousand, Hundred, Ten, One tenth, One percent and One thousandth.

1k is one thousand, 1m is one million, and 1b is one billion. Don't say that the computer unit 1b is one billion, bilion is one billion, and 1b is 1bilion. There are even larger units of quantity. First, the above figure is a self-multiplying system, which is 1 billion, 1 billion is trillions, and trillions is Beijing. Archimedes of Greece also adopted this system.

Archimedes:

Archimedes, a great ancient Greek philosopher, encyclopedic scientist, mathematician, physicist and mechanic, is the founder of statics and hydrostatics and enjoys the reputation of the father of mechanics. Archimedes, Gauss and Newton are listed as the three greatest mathematicians in the world.

Archimedes established the basic principles of statics and hydrostatics, and gave many methods to find the center of gravity of geometric figures, including the center of gravity of a figure surrounded by a parabola and its parallel chords.

Archimedes proved that the buoyancy of an object in a liquid is equal to the weight of the liquid it displaces. This result was later called Archimedes' principle, and he also gave a criterion for the balance and stability of a positive parabola rotating body floating in liquid.

The machine invented by Archimedes has a water spiral for diverting water, which can pull the lever pulley machine for loading large ships and explain the running models of the earth, the moon and the sun.
