Some more difficult problems are tackled in this lesson, as there is a carry-over when these numbers are added. The same principles apply, but a bit more thinking is required in these problems. A bunch of good examples are shown, and the abacus really helps you see what is going on very clearly.

I am taking a class via correspondence and the book is horrible. I am so thankful to have resources such as this describing what I need to learn. I don't think I would pass with out it! I love it! This video, and all videos by Perez, are awesome. As an adult learner, I really connected to his explanation and humor!
