I show you how to use an easier, helping problem to add a three-digit and a single-digit number, such as 435 + 6. We simply add 35 + 6 first, to get 41. The answer to the original addition problem is then 441.
Then we look at two problems, such as 194 + 8, wherethe answer will go over to the next hundred.
