Mastering Integer Exponent Rules

Mr. Buffington introduces integer exponents, focusing on negative exponents and the exponent rule for same bases. He explains how negative exponents move numbers and become positive, and demonstrates the rule with examples. The zero exponent rule is also covered, showing why any number to the power of zero equals one. A word problem illustrates the practical application of these rules, emphasizing the importance of having the same base to add exponents.
