Mathematical Concepts and Exponents

This video tutorial covers the concept of magnitude in mathematics, explaining how it relates to both large and small measurements. It delves into the use of positive and negative exponents to express these magnitudes and explores the relationship between exponents and place value. The lesson includes exercises to reinforce understanding and concludes with an exit ticket to assess comprehension.
