Prime Numbers and Distributive Property

Miss Dietrich explains how to solve a problem involving bagging spices using the greatest common factor (GCF) and the distributive property. The lesson involves calculating the total teaspoons of cinnamon and nutmeg, finding the GCF using prime factorization, and determining how many bags of each spice are needed. The video also includes verification of calculations and an explanation of the distributive property.
