This math topic focuses on algebraic function variable substitution, specifically dealing with bracketed terms that include negatives. It involves substituting given values for variables in algebraic expressions and then simplifying them. The skill practiced here is critical for understanding how to handle negative integers in algebraic contexts. Each question presents a different algebraic equation with specific values for the variables, asking students to find the result after properly substituting and performing the necessary arithmetic operations. This includes multiplying the substituted values and applying the correct arithmetic rules for dealing with negatives.
