I can do fairly complex calculations in my head and that is exactly the method I've used all my life. I'm glad to see it's been formalized.
It's easy to poke fun at something you don't understand. Do you move your lips when you read?
Yes, but how can you do these complex calculations? Because you learned the correct way of calculating them as a child. Forcing kids to use shortcuts that, as adults, are commonplace, doesn't work when the kid doesn't know the basics of mathematics. This is the reason common core math is a failure.

In addition, not every single person uses mental shortcuts the calculate problems the same way. We use what our minds comprehend the best. Standardizing it will only force 1 way of "learning" math, and will be largely inconsistent and will ultimately fail children.
Any rational intelligent human can see this. Layabout can not.

wrote memorization may be how you and i learned the first time, but it's not the "correct" way

what exactly makes wrote memorization a "basic" of math?
