Fraction Calculator - with step by step explanations

Calculating instruments, especially body parts (counted on the fingers), were used today as the final in prehistoric times. There are so many variations. In addition to counting ten fingers, some cultures have counted fingers, fingers, and thumb fingers between fingers, with fingers. Oxfen culture of New Guinea uses 27 upper body locations to represent the number.

To get statistical information, the length of the carved wood is used in wood, bone and stone since ancient times. Stone Age, including local Indian groups, uses lengths for gambling, personal services, and merchandise.

Sumerian invented a method for maintaining numerical data between the soil between 8000 and 3500 BC. It was made with small clay coins of various sizes, surrounded by pearls like string. Gradually, at the beginning of approximately 3500 BC, the ground markers were replaced by the number of signals which were affected by rounded pins in bullets (originally containers for chips) at the bottom, which were later fired. Approximately 3100 BC written numbers were separated from the numerical number and formed an abstract number.

Between 2700 and 2000 BC, in Sumer, the round styles were gradually replaced by Reed Styles, which sent wide-wing-shaped signals to the soil. The wedge shaped signals gave similar signals to round-top signals, and kept sign-valued signals for round-number signals. These systems are gradually converted to normal saxacimilium system; It was a place value system with only two affected points, vertical waz and chevron, which could present variety. The Caucasian blood system was fully developed at the beginning of the ancient Babylonian period (about 1950 BC) and it became standard in Babylonia.

Saxgasmal Digit was a mixed radix system that had alternate base 10 and 6 in the order of the veg shaped vertical volts and chips. Until 1950 it was a transit process. Collective numbers were often used in trading, but they were used for spatial and other calculations. This system was exported from Babylon and used throughout Mesopotamia, and every nation of the Mediterranean nations used standard Babylonian units and calculations, including Greeks, Romans, and Egyptians. In modern societies, the Babylonian style sex segment number is used to measure duration (minute per minute) and angle (degree).

In China, the number of military and commissions was calculated based on the modular length of the first. A unique number of soldiers and travel agents appear as a long time unique combination. The essential feature of the modular arithmetic is that it is easy to multiply, however addiction is very difficult. It uses modular arithmetic especially for strict decisions. It is difficult to multiply and share the traditional length. In modern times, modular arithmetic is sometimes used in digital signaling process.

The oldest Greek system has ethanean numbers, but in the fourth century BC, in the fourth century BC They used Quasidasimilar Alphabet system (see Greek numbers). The Jews used similar systems (Hebrew figures), in which the oldest example is about 100 BC. Just like coins are known.

The Roman Empire used wax, papyrus and longevity on the stone, which strictly adhered to the Greek tradition of assigning letters to different numbers. Until the 16th century, the Roman numerical system was common in Europe, when the local signal was commonly used.

Central America's Maya used the mixed base 18 and base 20 system, which was probably inherited from the Olmec, in which there were advanced indicators such as a status signal and zero. He used this system to perform advanced astronomical calculations, which included a precise count of solar lengths and Venus orbits.

The Inan Empire used Quippo to carry a large command economy, which produces the length of the composition formed from the fibers. Knowledge of coding of tumors and colors was suppressed and not alive by the Spanish conqueror in the 16th century, although still easy QUPU-like recording devices are used in the Andean region.
