It finishes arithmetic with mastery of advanced computational skills and introduces algebraic terminology, concepts, and problem-solving methodology. This course achieves the latter through mastery of first-degree relations with one variable.

The Supplemental Exercises provide additional exercises for every lesson in Memoria Pre-Algebra. Use them as further examples for illustration, for extra practice as needed, or for summer review material to help students maintain their skills. This Solutions Key provides answers for every problem.
