For science‚ algebra is used in astronomy‚ physics and chemistry. Astronomers and physicists use algebra to research and understand the universe. They observe‚ measure‚ interpret and develop theories to explain what is happening in the universe (US Bureau of Labor‚ 2009). One way that chemists use algebra is when mixing together chemicals. They need to calculate the correct amount of each substance to obtain the desired result. Algebraic Concepts in Everyday Life The following are examples

Contribution of India in mathematics The most fundamental contribution of India in mathematics is the invention of decimal system of enumeration‚ including the invention of zero. The decimal system uses nine digits (1 to 9) and the symbol zero (for nothing) to denote all natural numbers by assigning a place value to the digits. The Arabs carried this system to Africa and Europe. 1) Aryabhata is the first well known Indian mathematician. Born in Kerala‚ he completed his studies at the university

in the usual decimal notation (see the table for its representation in some other bases). The constant is also known as Archimedes Constant‚ although this name is rather uncommon in modern‚ western‚ English-speaking contexts. Many formulae from mathematics‚ science‚ and engineering involve π‚ which is one of the most important mathematical and physical constants.[5] π is an irrational number‚ which means that its value cannot be expressed exactly as a fraction m/n‚ where m and n are integers.
