I often see or hear that people don't do math(s). They treat it as if it is some kind of specialized information. I'm in a field where I use it frequently at work, and it was used extensively in post secondary education. Even outside of that I feel like it's pretty handy in many situations. Maybe it is ubiquitous access to pocket computers that helps people feel like that. I didn't grow up with them, so maybe that colors my perception.

So, purely for mental mathematics, deliberately leaving complexity aside, what is your frequency of use?
