Expressing in algebraic form is the beginning of the mathematical basis, as a mathematician is not a calculator. The mathematician works with general and non-specific ideas. For example, when we express “two more than five”, it is a specific thought, as we are adding two to five. In mathematics, thinking is more general, in the example mentioned above, a mathematician says “two more than $x$”. $$x+2$$In this case, we add “two to any number $x$”, where this number can be included in the set of natural numbers
