Algebra

Algebra is a branch of mathematics in which arithmetic operations are generalized and applied to variable quantities and specific numbers. In our schooldays we use algebra to solve polynomial equations whereas professional mathematicians physicists economists and computer engineers use algebra to study abstract mathematical structures with the properties of addition and multiplication. Both elementary and higher algebra stipulate that only a certain number of quantities should be involved in the calculations and the calculations should end after a certain number of steps. Both forms of algebra are abstract in nature using letters to represent variables. Modern algebra which has been used in the 20th century to solve so many mathematical and scientific problems evolved from the work of the 19th century French mathematician Evariste Galois. Many algebraic concepts such as the theory of groups have influenced fields such as quantum physics whereas computer science is totally based on Boolean algebra. Psychologists and economists use matrices and linear algebra in linear programming. However before any child can dream of becoming a mathematician economist physicist computer scientist or psychologist they have to study algebra in school. This is when most students learn about the various classes of numbers and also learn how...
