Properties and Operations of Multiplication

In this video, Pak Beni introduces the third part of the series on integers, focusing on multiplication and division. He explains the basic rules, such as when the signs are the same, the result is positive, and when different, the result is negative. The video covers the commutative, associative, and distributive properties of multiplication. Pak Beni also discusses the order of operations and demonstrates solving a word problem involving integer operations. The video concludes with a preview of the next topic on comparing fractions.
