what math do you use regularly?

The calculus thread got me thinking about what math I have used in my life since undergrad. Since I am not in a STEM field I have used calculus VERY rarely, maybe 3-4 times with acoustics but I could have arrived at a value good enough for my purposes by eyeballing the data.
I use geometry/trig fairly often and understanding logarithms occasionally comes in handy. I also use basic algebra a lot but I think everyone does even if they don't see their thought process as algebra. The understanding of stats comes in handy too.
Curious what math other people use regularly.

basic bitch math 
I haven't used algebra/trig/geometry since high school.

The calculator hot key.
I use the hell out of algebraic, geometric, and, to a lesser extent trigonometric concepts.

Nutrition facts per serving times number of servings in a container. I’m somewhat of a mathlete.

A lot of basic algebra. A decent amount of statistics. Calculus rarely.

Basic percentages, and simple addition and subtraction in work.
At home, geometry and physics.
I've always had a knack for spotting failure points. Calculating leverage. That sort of thing.

Simple math is all I use. 2+2 or 4x4 and a prectage here and there.

I use a lot of calculus, linear algebra, and higher mathematics, but I'm an engineering professor, so a lot of times it's just because I have to teach it.

Yeah I’m fricked on those. I use them with ease but don’t ask me to create one.

3.50, 420, 69, F250 are the only numbers that matter

Rarely actually plug in numbers and grind out a result, but I find having a broad math background makes my “guesstimates”fall more in the ballpark.

Can someone please provide a real life situation outside of work where you would ever use pi, sine/cosine or any trig concepts, or my personal favorite standard deviation or whatever other BS I memorized temporarily in statistics class back then?

Addition. Watching my paper stack and counting them hundreds.

These arent the same but sure. Stats are used in all these dumb survey testing,or trying to extrapolate polls.
things like standard deviation or descriptive statistics can be used in stocks and volatility.
I'm not in finance but finding all the diff ratios can show your company's performance in certain ways.

I work primarily with A.I. and machine learning developers, electrical engineers and physicists, so probably a lot of abstract linear algebra.

You never build anything where the area or circumference of a circle is useful? The same with knowing the length of a or all sides of a geometric shape? I have calculated the hypotenuse of a triangle many times when I was building things.

standard deviation
Is it not helpful in understanding data knowing what an average, mean and standard deviation are and how they are derived? I feel like I run into these concepts fairly regularly.

I solve simultaneous equations quite a lot but it's usually the same thing every time and I use templates I've made myself or gotten from somewhere else. After the initial work, it's just plugging in numbers.
