<p>I have a PhD and lots of graduate level math background, and still use my math skills quite a bit at work so that makes a big difference (but if I don’t use it, I lose it, until I read up on it again). Hubby, however, also a PhD but in more quant field is so much more clever, fluent, faster, more helpful than I am. He is the math guy in our house.</p>
<p>Despite my name I only did two semesters of college calculus. I can still do algebra, I have used trig for my work though not much lately. (I can do nearly everything I need just using the Pythagorean theorem.) I still know what calculus is, and can recite the fundamental theorem (It was my yearbook quote), but I couldn’t do a calculus problem if I had to. I’ve always enjoyed probability though I have to relearn it regularly. Percentages - ugh - I had to use them all the time when I worked for an interior designer and everything was discounted off some theoretical list price.</p>
<p>I occasionally have surprised myself by being able to figure out geometry problems quicker than anyone else in the house. I guess there’s a reason I went into architecture!</p>
<p>MS in structural engineering. I had to to take calculus and differential equations. I find that I’ve forgotten a lot of it, but when I look at the textbook for a few minutes, I can understand it. Actually, I’m surprised that a lot of it makes more sense to me now than it did then! I’ve been able to help DS with AP Physics problems that seemed impossible 30 years ago.</p>
<p>I didn’t have high level math in college - just 2 semesters of Calculus and a semester of Statistics (business major). I remember some statistics, and I could still differentiate a simple equation, but that’s about it. I have a very good grasp of basic algebra and I have excellent arithmetic skills (which qualifies me to help with 4th grade homework). I don’t remember much of the math my HS D’s are learning now. DH is a math whiz and can do any problem the D’s have. Somehow he retained all of his math.</p>
<p>PhD in a math-related field sometime in the dark ages, but don’t haven’t used math as part of my work for a very long time. Helped my son with BC Calculus (but I had to read the book to remember some of the things) and AP Physics last year. I would have to relearn much beyond 2nd semester calculus [I had classes in multivariate calculus, real analysis, probability theory, mathematical statistics, operations research, game theory, college-level algebra, differential equations, partial differential equations, and probably others I can’t remember]. I’ll help my daughter this year with statistics.</p>
<p>MA in English; took zero math past high school. Can still do Algebra I stuff (factoring polynomials, etc.) and plane geometry, but that’s about it.</p>
<p>Was visiting niece and nephew this evening, niece is in 7th grade, she couldn’t understand dependent/independent variables.SIL and I start explaining variables thinking we are doing a great job remembering early algebra from 25-30 years ago.Niece is looking dumbfounded. </p>
<p>My 14 year old laughs and rolls her eyes and chimes in, "Ummm, she is doing her science homework, not math. Let me explain it to her. "</p>
<p>We both crawled under our respective rocks till the math lesson officially begins.</p>
<p>Took calculus as a senior in high school and again as a senior in college, just to prove to myself that I could. I remember absolutely nothing now; couldn’t solve a problem if my life depended on it. I remember some of geometry and algebra. </p>
<p>I took French for 6 years, and remember just a few words, and there are many books I read for English that I have totally forgotten. In theory learning all those things that I have long since forgotten improved my critical thinking skills. I sure hope so, because I would hate to think I suffered through all that math for nothing.</p>
<p>MD. </p>
<p>Somewhere around 7th grade, daughter says “I understood it until you helped me”. In my work, I don’t even try to add and subtract without a calculator. No math confidence. I sorta know when something is wrong, though.</p>
<p>My mom only took 1 year of algebra in high school and took no other math in her life, but I think she remembers a good amount of it.</p>
<p>BS in biochemistry.
Haven’t done maths in 30 years, but scored 800 on a practice GRE I took for fun this summer.</p>
<p>BS in science, took one semester of college calculus, which I really enjoyed, but remember none of it. Also took probability and statistics, which I found pretty easy. But I apparently cannot subtract, as when figuring out mileage for different parts of my recent bike tour, I figured I was riding 18.5 miles the day I was starting at mile marker 60 and riding down to mile marker 35. Yeah. And then I posted that number on a little map of my journey on my office door.</p>
<p>:: takes the tall pointy hat and stool and heads to the corner ::</p>
<p>M.A. in English. Quit math after I got a C- in algebra II in 10th grade. Had to take trig in college and also got a C-. I like math, but never did the homework. And I had the worst teachers ever. I homeschooled my older kids, but they took precalc/calc classes at school. They did well–I guess the teachers are better nowadays 
I’m great through algebra I. I see no reason for anyone except future engineers to go beyond that. Our math curriculum makes no sense. Statistics and bookkeeping/accounting would be so much more useful for 95% of students.</p>
<p>I always struggled in math. Sadly so does one of my sons. However in working with him 30 years later, suddenly in all makes sense! I find algebra strangely beautiful, almost poetic. Did something change cognitively in me or did the texts get better? Now I went to public schools in the 70’s in Florida so it is amazing that I am literate!</p>
<p>Marge: When I was in school, I loved math. Until…
[flashback to Marge studying with a calculus book on the beach]
Homer: Hey, Professor Von Hubba Hubba - wanna hop in my dune bug and erode some beach?
Marge: I’d love to. But I’ve got my calculus final tomorrow.
Homer: C’mon, baby, the only math you need is You + Me = Forever.
Marge: Oh, Homie. [She leaves with him.]
[Present day] Marge: Since then, I haven’t been able to do any of the calculus I’ve encountered in my daily life. But that’s not going to happen to you!</p>
<hr>
<p>Took everything through calculus but would need a major refresher to do calculus and most trig.</p>
<p>I was able to help my D. thru HS calc. Given textbook, I believe I could figure out whatever. My H. is the same. I have never needed to use math in my job. The way I was taught in school was way different than the way kids are taught in k-12 system.</p>
<p>Took calculus in high school (or was probably pre-calculus); managed to avoid all math classes in undergrad, but had to take a bunch of math (including calculus) in grad school (MPA). Have always hated math but could study my way to an A under duress. My job includes a lot of financial analysis spreadsheet work but really nothing a middle schooler couldn’t do. I use Excel or my calculator to add 2+2.</p>
<p>H on the other hand loves math. He was able to help both boys through calculus in high school just by figuring out more than remembering. He doesn’t use any math in his job. Has a master’s degree in economics and law degree. Both boys are studying engineering, enjoy math, and are adept but in no way exceptional in terms of their math skills.</p>
<p>I remember pretty much everything my 9th grader has brought to me so far, a review of algebra 1 for his geometry class. Unfortunately though, I’m one of those who does the problem completely wrong but still manages to come up with the right answer somehonw. It looks like my son is taking after me in that regard. ~sigh~
I’m a college drop out. In what should have been the fall semester of my junior year, I just hung out on campus with my calculus book and studied from that until I got the nerve to tell folks (parents) that I was no longer a student. When I decided to go back to school umpteen years later, I placed into precalc and aced it. It wasn’t until this precalc class that I took concurrently with physics that I finally “got” vectors and trig. I had taken both elementary functions and physics in high school.</p>
<p>Answer to OP: </p>
<p>Right now, about 70% of what I learned.
If I spent a couple of days brushing up: 90%.</p>
<p>I only did a little bit of Calculus.</p>
<p>I can get most of the SAT-! Math questions. I would not do well on the Math II subject test, though.</p>
<p>I really expected better of math majors than this:</p>

<p>Maybe you can tell us from which universities you graduated?</p>
