Trunks, Pilaf, Shu and Mai are in math class, and the teacher calls on Trunks to solve a math problem. As Trunks thinks out loud, Pilaf interrupts him and explains the correct approach. This clip is from the episode, "Hope! Redux Awaken in the Present, Trunks."
This clip can be used to teach math, more specifically order of operations. The math problem is (1000 - 900 * 0.5). Trunks attempts to subtract 900 from 1000 first, but Pilaf interrupts him and correctly states that he must multiply 900 by 0.5 first then subtract the result from 1000. To make his point more tangible, Pilaf uses an example involving a sale. If an item is 50% off, you would discount it first then subtract the amount of money you have (1000) by the discounted price (900 * 0.5 = 450). Pilaf's arithmetic is correct, and he arrives at the correct solution: 550.
