These questions led extending algebra to non-numerical objects, such as permutations, vectors, matrices, and polynomials. Then more general questions, such as 'does an equation have a solution?', 'how many solutions does an equation have?', 'what can be said about the nature of the solutions?' are considered. Historically, and in current teaching, the study of algebra starts with the solving of equations, such as the quadratic equation above. That is to say, to find all the solutions of the equation. For example, in x + 2 = 5 which satisfy the equation.

Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.Д®lementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. The more basic parts of algebra are called elementary algebra the more abstract parts are called abstract algebra or modern algebra. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols it is a unifying thread of almost all of mathematics. The quadratic formula expresses the solution of the equation ax 2 + bx + c = 0, where a is not zero, in terms of its coefficients a, b and c.ДЄlgebra (from Arabic: Ш§Щ„Ш¬ШЁШ±вЂЋ, romanized: al-jabr, lit.'reunion of broken parts, bonesetting ') is one of the broad areas of mathematics, together with number theory, geometry and analysis.
