Yikes.

What is so hard about taking a 9 and adding a 6 to it. Their way looked more complex. Break the 6 down to 5 + 1. That works great unless you are adding it to something other than a 9. You have to take x (x = 9 in this case), subtract it from 10, then subtract that difference from y (y = 6 in this case), and the difference of that calculation added to 10.

That's damn complicated to me.

Don't get what they said about memorizing 9 + 6 = 15. If you don't understand how to take 9 and add 6 to it and get 15, then this new process is going to completely blow some kids mind.

Don't think this is going to do the average school kid much good.
