This math topic focuses on calculating the ones digit of a product involving large exponent values. Specifically, it involves multiplying numbers raised to large, different exponents and then identifying the ones digit of the result. The problems are structured to enhance the learners’ understanding of patterns in last digits when numbers are raised to powers, an essential skill that combines elements of number theory and modular arithmetic. Additionally, this area is a part of a broader unit on digits and divisibility.
