Adding and Subtracting 9 🤔 MENTAL MATH for Kids 🚀 Episode 4

Educational video for kids that talks about how to mentally add and subtract 9 in a quick and easy way. When we need to add or subtract 9 to a two-digit number, instead of doing it longhand, which can take more time, we can use a very simple trick. For example, let's add 9 plus 12. To do this, the first thing we are going to do is add 10 to 12, which gives us 22. Then, we simply subtract 1, and we get 21 in total! This video is a very useful and interesting resource for children. This trick makes mental math easier and helps you to get the result faster. It is an excellent video for elementary school.
