Algebra: Unlocking the Secrets of Unknown Values

TLDRAlgebra is a branch of math that introduces the element of the unknown, represented by symbols. Solving algebraic equations requires simplifying and rearranging them to find the values of the unknowns. In algebra, the same symbol can represent different unknown values in different problems, but it can't represent different values at the same time in the same problem. Multiplication is the default operation in algebra, and the multiplication sign is often not shown. Algebra is useful in various fields like science, engineering, economics, and computer programming.
