This math topic focuses on evaluating polynomial expressions involving basic algebraic manipulation and arithmetic without the use of a calculator. The problems require simplifying expressions of the form (n² + n + (n+1)) / (n+1), where n is an integer. Each question provides the expression with different values of n and offers multiple choice answers. The exercises are structured to strengthen understanding of polynomials, quadratic expressions, and the simplification of algebraic fractions within an advanced context.
