The number glyphs were: a stroke, or staff, for one; a heel bone for 10; a coil of rope for 100; a lotus flower for 1000; a pointing finger for 10,000; a borbot fish (or tadpole) for 100,000; and an astonished man for 1,000,000.

Clearly their number system was a base ten system; however, they used a simple grouping system rather than a positional system. They were originally four-wheel vehicles drawn by slow-moving animals.

Despite the limited surveying tools of the time, it is reported that no side is more than 8 inches different in length than another. The Sumerians represented the integers using cuneiform wedge patterns.

For about 4500 years it was the tallest building in the world. There is much speculation on exactly how this pyramid and its companions were actually constructed. They used a vertical wedge to represent a unit and a sidewys wedge to represent ten units.

With arrangements of these two symbols they could represnt numbers of any size.

If the Sumerians wanted to represent our number 10,884, they would put three closely spaced vertical wedges followed by a space and then one vertical wedge followed by a space and finally two sideways wedges and four vertical wedges closely spaced to each other. The Rhind Papyrus is located in the British Museum.

This represented 3(60The Moscow Papyrus is located in the Museum of Fine Arts in Moscow whence its name. It was brought to Russia during the middle of the 19th century. This document was possibly copied from another document dating to around 2650 B. This document is one of the primary sources of early Egyptian mathematics.

The Rhind Papyrus (AKA the Ahmes Papyrus) is named after the Scottish collector, Henry Rhind, who acquired it in 1858. Catastrophe in Crete (Three dates are reported: 1380, 1450, 1628 B. The catastrophe was the eruption, and resulting tsunamis, of the Satorini Volcano (also known as Thera) in the Aegean Sea.

This eruption is considered to be one of the largest in the last 10,000 years and is the probable cause of the end of the Minoan civilization.

The angles between two intersecting straight lines are equal. All knowledge and discoveries were attributed to Pythagoras. E.), the Persians, under the leadership of King Cyrus, took Babylon, the ancient capital of a middle eastern empire covering modern Iraq, Syria, Lebanon, and Israel, and thus became masters of Western Asia. E.) Parmenides was Greek philosopher who was a follower of Pythagoras. Philosophers of his time considered his philosophy to be quite negative.

Two triangles are congruent if they have two angles and one side equal. The rule that probably had the most impact on the history of mathematics was that all members of the brotherhood should observe strict loyalty to Pythagoras and the brotherhood and maintain secrecy. A remarkable aspect of the capture of Babylon is the fact that Cyrus allowed the Jews (who were exiled in Babylonia) to return home. He was an early believer of a cosmology that consisted of a spherical earth and a finite, motionless, spherical universe. Zeno wrote a book that reportedly contained forty paradoxes concerning the continuum.

All these troubles caused Pericles to lose his popular support and he was deposed from office; however, a few weeks later the people repented and he was reinstated with greater powers than before. dates are approximates) Hippias was knowledgeable in many areas.
