Multiplying Negative Integers by Positive Integers

This video tutorial teaches how to multiply a negative integer by a positive integer using the concept of equal groups. It explains multiplication as increasing a number by a specified scale and introduces models to represent positive and negative integers. The tutorial uses a product box to demonstrate solving multiplication problems, starting with a neutral field of zero pairs. By removing positive groups, the tutorial shows how to achieve negative products, providing examples like -5 * 3 and -7 * 2, resulting in -15 and -14, respectively.
