Standard form is a way of writing an algebraic expression in which the terms are arranged in order from the term with the highest degree (or exponent) of the variable to the term with the lowest degree (or exponent) of the variable. The variable is usually represented by the letter x. To convert an expression to standard form, you must combine like terms and simplify the expression as much as possible.
Converting expressions to standard form is important because it makes it easier to perform operations on the expression and to solve equations.
