The basic mode of algebra is to develop rules for handling unknowns coefficients and numbers and exponents.The long term advantage is that the same rules apply to trigonometry and calculus. The basic letter variables of Algebra are usually x.y.z and a,b,c. Any letter can be used depending on the application required. The Algebraic variable is constant for the length of the solution. In a further example the constants representing the variable will change while the formula will be reused for different initial and final conditions.In summary, In algebra problem the attribute is that the variable stays the same for the length of the solution. In the next problem we can use the same formula but different coefficients which will result in a new solution.In trigonometry the attributes of the variable have the characteristics of trigonometry but the algebra rules are the same.In calculus the variable is constantly changing according the rules of calculus. Again the basic rules of Algebra are the same but the attributes of the variables follow the rules of calculus.
