๐ Topic Summary
Adding multiples of 10 is a fundamental skill in mathematics. Multiples of 10 are numbers like 10, 20, 30, and so on. When adding them, we're essentially counting groups of ten. For example, if you have 20 apples and someone gives you 30 more, you can quickly find the total by adding 20 + 30.
This skill makes mental math easier and faster. Understanding this concept will help build a solid foundation for more complex arithmetic.
