Multiplying by 10 is like taking a shortcut in math! When you multiply any number by 10, you simply add a zero to the end of that number. For example, if you have 5 and you multiply it by 10 ($5 \times 10$), you get 50! This works because we're moving the number one place to the left in the place value system.
Understanding this trick makes mental math much faster and easier. It's also a building block for more complex multiplication and division problems you'll encounter later on. So, let's dive into some practice and master this important skill!
