The Greek word abax, which refers to a counting board.
What does the Greek word 'abacus' come from?
ORIGIN late Middle English (denoting a board strewn with sand on which to draw figures): from Latin, from Greek abax, abak- 'slab, drawing board,' of Semitic origin; probably related to Hebrew ' āḇāq 'dust.'

What did the first computers perform?
The first computer was an Chinese abacus. A computer is defined as A device that computes that assembles, stores, correlates, or otherwise processes information. An abacus is a manual computing device consisting of a frame holding parallel rods strung with movable counters. Word History: The adjective dusty, with its connotations of disuse and age, might seem an appropriate word to describe the abacus, since this counting device was used for solving arithmetical problems in the days before calculators and computers. Originally the abacus was, in fact, dusty. The source of our word abacus, the Greek word abax, probably comes from Hebrew 'bq, "dust," although the details of transmission are obscure. In postbiblical usage 'bq meant "sand used as a writing surface." The Greek word abax has as one of its senses "a board sprinkled with sand or dust for drawing geometric diagrams." This board is a relative of the abacus with movable counters strung on rods that is familiar to us. The first use of the word abacus, recorded in Middle English in a work written before 1387, refers to a sand-board abacus used by the Arabs. The difference in form between the Middle English word abacus and its Greek source abax is explained by the fact that Middle English borrowed Latin abacus, which came from the Greek genitive form (abakos) of abax.
How do you derive mean of Pareto distribution?
You must know calculus, at least that the integral of xN = 1/(N+1)xN+1 . Define the Pareto distribution as: f(x) = abax-(a+1) or Cx-(a+1) where C = aba (a constant) Remember that the pdf is defined over the domain [b, inf] otherwise zero. Mean = integral xf(x) evaluated from b to infinity. Remember also that the limit of 1/x as x goes to infinity = 0. Similarly for any positive a, (1/x)a goes to 0 as x goes to infinity. mean = integral C x-(a+1)x dx = integral Cx-a = C(1/(-a+1))x-a+1 evaluated over the interval b to infinity. The integral is zero at infinity, so the mean = C(0-1/(-a+1))b-a+1 Remember b-a+1 = b-ab After substituting and cancelling mean = ab/(a-1) for a greater than 1.
What is the history of the abacus?
The abacus is an ancient calculating tool with a history spanning over 3,000 years. Its name derives from the Greek word "abax" or "abakon," meaning "tabular form," possibly originating from the Semitic word "abq," meaning "sand." Evolution of the Abacus Origins (circa 300-500 BC): The exact origin of the abacus is not definitively established, but it is believed to have been invented between 300 and 500 BC. Chinese Abacus (Suanpan): Early versions featured a 2/5 bead configuration, which was complex and later simplified. Japanese Abacus (Soroban): Mathematician Seki Kowa modified the abacus to a 1/4 bead configuration, leading to the modern Soroban used today. Today, the abacus is not only a manual calculator but also a powerful brain development tool. At Mastermind Abacus, we integrate this ancient instrument with modern teaching methodologies to enhance mathematical skills and cognitive abilities in learners.
Where was the first abacus used?
The first reported and substantiated use of an abacus, or abacus-like instrument was in Sumeria between 2,700 and 2,300 BCE - or roughly 4,700 years ago. This used a table of columns with each column equivalent to an order of magnitude above the previous column; just as we would have columns for x10, x100, x1000, x10000. During the next 2000 years various forms of this came into common usage across areas of the world (Mesopotamia, Persia, Egypt, India, China, Greece, Rome). Some were similar in appearance, while others used the same principals, but looked slightly different. For example the Roman abacus used a clay tablet with columns and counting stones (a counting board), while the Chinese version looked almost identical, but had fixed string columns with counting stones attached to them - similar how most people picture an abacus. The spread and variance in design of the abacus is probably due to the movement of early traders across the early trade routes (Silk Road etc.). The abacus is still made extensive use of today, as they are simple to use, fast and don't require batteries to operate them. The word abacus comes to us by way of Latin as a mutation of the Greek word abax. In turn, the Greeks may have adopted the Phoenician word abak, meaning "sand," although some authorities lean toward the Hebrew word abhaq, meaning "dust." Irrespective of the source, the original concept referred to a flat stone covered with sand (or dust) into which numeric symbols were drawn. The first abacus was almost certainly based on such a stone, with pebbles being placed on lines drawn in the sand. Over time, the stone was replaced by a wooden frame supporting thin sticks, braided hair, or leather thongs, onto which clay beads or pebbles with holes were threaded. A variety of different types of abacus were developed, but the most popular became those based on the bi-quinary system, which utilizes a combination of two bases (base-2 and base-5) to represent decimal numbers. Although the abacus does not qualify as a mechanical calculator, it certainly stands proud as one of first mechanical aids to calculation. Both the abacus and the counting board are mechanical aids used for counting; they are not calculators in the sense we use the word today. The person operating the abacus performs calculations in their head and uses the abacus as a physical aid to keep track of the sums, the carrys, etc. What did the first counting board look like? The earliest counting boards are forever lost because of the perishable materials used in their construction. However, educated guesses can be made about their construction, based on early writings of Plutarch (a priest at the Oracle at Delphi) and others. In outdoor markets of those times, the simplest counting board involved drawing lines in the sand with ones fingers or with a stylus, and placing pebbles between those lines as place-holders representing numbers (the spaces between 2 lines would represent the units 10s, 100s, etc.). The more affluent people, could afford small wooden tables having raised borders that were filled with sand (usually coloured blue or green). A benefit of these counting boards on tables, was that they could be moved without disturbing the calculation- the table could be picked up and carried indoors. With the need for portable devices, wooden boards with grooves carved into the surface were then created and wooden markers (small discs) were used as place-holders. The wooden boards then gave way to even more more durable materials like marble and metal (bronze) used with stone or metal markers.
