The video tutorial covers the distributive property, explaining how it simplifies multiplication by distributing a factor over a sum or difference. It provides examples using both addition and subtraction, demonstrating how to break down complex multiplication into simpler mental math. The lesson includes guided practice problems and explores alternative methods for applying the distributive property, concluding with a summary of key points.
