Algebra is a branch of mathematics dealing with equations and expressions involving unknown variables. An equation is an expression with at least two parts where one part is known (the variable) and the second part is to be determined. These types of equations are called algebraic equations and have different forms depending on how they are written. A general algebraic equation may look something like this: x 2x + 4x – 4x + 8x – 16x + 32x – 32x + 64x – 128x. This expression contains three terms and each term equals x plus some number multiple of x minus some number multiple of x. In the example above, the first two terms are 2x because they are multiplications of x by itself while the last two terms are 4x because they are multiplies of x by itself again. visit book364 for more books.
