Normal type is a means of writing an algebraic expression by which the phrases are organized so as from the time period with the best diploma (or exponent) of the variable to the time period with the bottom diploma (or exponent) of the variable. The variable is normally represented by the letter x. To transform an expression to plain type, you have to mix like phrases and simplify the expression as a lot as attainable.
Changing expressions to plain type is vital as a result of it makes it simpler to carry out operations on the expression and to resolve equations.
