Not a super big fan, honestly. I'm a bit horrified when I see high school seniors who are smart, and have been through the entire HS math sequence... dig around in their backpack for a calculator to find 5 times 1.5 or 20% of 11.

I'm glad that we have calculators and computing devices, but I'm not glad that they have made teens with basic numeracy into an endangered species. Many tools we use expand our understanding, but the calculator causes our arithmetic skills to atrophy.

From my experience, the more advanced math you learn, the worse you become at arithmetic. I knew a lot of math majors in college, and all of them used calculators all the time.

Yes, I've gotten worse at arithmetic, too.

The point is, one is hard pressed to find anyone who can do much arithmetic-- even trivial things.
