Finding triple of 400 quickly

To find the triple of 400, the key step is to multiply 400 by 3. Tripling a number means you combine three copies of the number together, which multiplication simplifies into one operation. So, instead of adding 400 three times, you multiply it by 3. By performing the calculation 400 * 3, you directly obtain 1200, which represents the triple of 400. This straightforward approach ensures you can quickly and accurately calculate the triple for any number 400 without additional steps or complications. Understanding how multiplication works as repeated addition helps clarify why this method efficiently gives the desired triple value.
