### Algebra - Collaboration research work ( Sean Chiu , Chelsea , Qayyum , Bryan Goh)

Al - Kwarizmi
Who was he ?

Khawarizmi was a mathematician, astronomer and geographer.
He was perhaps one of the greatest mathematicians who ever lived.
His contribution to algebra was substantial , almost making him sort of the founder or person who "made" algebra.
He not only launched the subject in a systematic form but he also developed it to the extent of giving analytical solutions of linear and quadratic equations, which established him as the founder of Algebra.

What are his contributions?

He launched the subject algebra in a systematic form but he also developed it to the extent of giving analytical solutions of linear and quadratic equations, which established him as the founder of Algebra. He introduced the Arabic numerals to Europe and made Algebra famous. He convinced European mathematicians to use these numbers as they are easier to use. He wrote a book called "Al-Jabr Wal' Muqibla", in which he introduced his own number system and introduced Algebra. TheRomans and Greeks named his books "So said Algorizmi". The word algorithm is also named after him.

Origins of algebra

It was not developed or invented by a single person but it evolved over the centuries.The  basics or traces of the beginning of algebra leads back to the Babylonians but it was further developed by Civilisations , any many people , like Al Kwarizmi.

What is algebra and how can it be applied to real life ?

Algebra is the part of mathematics in which letters and other symbols are used to represent numbers and quantities in formulae and equations. In other words , alphabets

are used to solve math questions and the alphabets are know as "unknowns".

How can it be applied to real life ?

Lets say you want to buy a Xbox. However , your budget is only \$800 . You know a new system costs \$400 and extra controller \$40. Assuming a game costs \$60 how many games could you get?

Let x= the number of Games

\$800 = \$400 + \$40 +\$60x
800=460+60x
360=60x
x = 6 Games
So that is how algebra is used in real life.
