The person you are replying to clearly stated that every grandma knows this, and yet you seem to have given up without even trying to ask a grandma.

- lproven 2y agoWell, this is true. I am 56, and my last living grandmother died over 30 years ago. I became a father 5 years ago, so strictly, my mother is a grandmother. I could ask her, but I am very confident she does not know. I have a science degree, and I just barely scraped through a statistics 101 course with great difficulty. I am pretty smart; I speak 6 foreign languages, and I have held down a career in software for approaching 40 years now, by understanding hard stuff and making it work, or documenting it, or explaining it. But I find algebra hard, just scraped through a mathematics 'O' level in 1986 by taking corrective classes and resitting the 1985 exam that I failed. I stand by what I said. I've never heard this rule. Looking at the Wolfram explanation, I could do that, yes. But I've never heard of this, and I am pretty confident my mother could not do this.
- _yb2s 2y agoI don't think it came across clearly but I was teasing the commenter you were replying to (and not you) for making an absurd claim in a confusing, sexist, and ageist way. Although my own grandparents are also dead, I know quite a few grandmas, including my stepmom (who had a ~5 decade career as a software engineer) - that are brilliant mathematicians and/or coders - so I take exception to the idea of using the word grandma as a stand-in for an ignorant person. Also, every person educated through public school in a wealthy country that isn't mentally disabled knows actual algebra and has studied it for 6+ years, not just the "rule of 3" whatever that is. However, I do want to say something about listing out your qualifications and experience like you did on here... in the petty power struggles and trolling on the internet it does the exact opposite of what it seems like it should. It's putting the other person in charge of deciding if you are "good enough" to participate or have an opinion, by implicitly making an effort to convince them and asking them to judge you. Your opinion and reasoning carry more weight on their own, without arguing why you should have the right to have them.
- lproven 2y agoHmmm. Well, if we all misread you, ISTM that you also misread me. What I was trying to say was: "I am pretty smart, but I can't do this." Which means: "different people are smart in different ways." Which means: "what is no problem for Lisp coders can be a pretty big problem for other folks."
