algebra in the study of a structure that does not belong to algebra. For example algebra of infinite series may denote the methods for computing with series without using the notions of infinite summation‚ limits andconvergence. The Hellenistic mathematician Diophantus has traditionally been known as "the father of algebra"[77][78] but debate now exists as to whether or not Al-Khwarizmi deserves this title instead.[77]Those who support Diophantus point to the fact that the algebra found in Al-Jabr

The scaffolding teaching strategy provides individualized support based on the learner’s ZPD (Chang‚ Sung‚ & Chen‚ 2002). In scaffolding instruction a more knowledgeable other provides scaffolds or supports to facilitate the learner’s development.

About two to three thousand years ago‚ the Golden Ratio was first recognized and made use by the ancient mathematicians in Egypt. The golden ratio was introduced by its frequent use in geometry. An ancient mathematician‚ sculptor‚ and architect named Phidias‚ who used the golden ratio to make sculptures‚ discovered it. He lived from sometime around 490 to 430 BC. None of his original works exist‚ however he was

Many people had tried to solve this and had failed‚ two notables who had tried were‚ Alfred Kempe (1879) and Peter Guthrie Tait (1880). Many mathematicians kept failing until around the 1960s – 1970s when German mathematician Heinrich Heesch developed a way to use computers to solve proofs. And by 1976 Kenneth Appel and Wolfgang Haken‚ at the University of Illinois had stated that they had proven the theorem. They had used two technical

There is the need to deal with simple geometrical situations in providing shelter and dealing with land. Once some form of writing is added into the mix‚ mathematics cannot be far behind. It might even be said that the symbolic approach precedes and leads to the invention of writing.Archaeologists‚ anthropologists‚ linguists and others studying

Euclid also known as Euclid of Alexandria‚ was a Greek mathematician who flourished in Alexandria‚ Egypt‚ almost certainly during the reign of Ptolemy 1 between 323 and 283 BC. Neither the year nor the place of his birth has been established‚ and the circumstances of his death remain a mystery. Little is known about Euclid other than his writings‚ the little information known about Euclid comes from commentaries by Proclus and Pappus of Alexandria. Euclid attended the great library of Alexandria
