Multiplying Integers

This lesson teaches how to multiply two integers by first multiplying their absolute values and then determining the sign of the product. If both integers have the same sign, the product is positive; if they have different signs, the product is negative. The lesson includes examples to illustrate these rules: multiplying -2 by 5 results in -10, and multiplying -9 by -11 results in 99. The video concludes with a recap of these concepts.
