This math topic focuses on practicing algebraic function variable substitutions with fractional terms that involve negative integers. It includes multiple problems that require calculating the value of algebraic expressions when given specific negative and non-negative values for the variables involved. Each problem presents a formula and asks for the solution using substituted values. The expressions are fractionally formatted and involve addition, subtraction, and division operations predominantly. The topic is ideal for reinforcing understanding of handling negatives in algebraic contexts and manipulating expressions with multiple variables.
