    It’s also a day without using anything he learned in art, or geography, or chemistry, or English literature, or history, or pretty much anything he studied in school after age 10. Why does math get singled out?

      Because math is abstract and difficult to relate to. We should be taught practical applications of the abstract concepts, and the exam questions should be more practical.

        yeah i think most of us were taught by people who didn’t “understand” math either, so we don’t really get what it is that we’re doing, we just memorize the process to get the numbers to match, which isnt fun at all. I had a very difficult time in school with math.

        When i was reintroduced to math functions as an electrician (and an adult) and the numbersoup actually described tactile, real world connections i had a much more fun time learning them.

        I demand only the practical parts of art and history be taught in school.

        Also - the questions that focus on practical applications are called word problems, and they get complained about more than anything else.

        The reason why they’re abstract and difficult to relate to is because we’re all being taught maths backwards.

        In science, a phenomenon is observed and then maths is used to create a set of equations describe it’s behaviour. Then using the equations, other experiments can be designed to prove other hypothesises. This is known as the experimentalist approach to science.

        Engineering is the same but less research and more application focused. For example, I need to design a wooden shelf that is A inches/meters long and supports B lb/kg of weight. How do I do that? Using trigonometry and Newtonian physics to work out the dimensions.

        Finance is often used for basic algebra and calculus.

        However, it is not always helpful to work in the material when using mathematics and the abstract is preferred. This is usually only useful for the theoretical approach in science, in theoretical mathematics, or at the cutting edge of engineering disciplines.

        If we were taught by being presented with a problem first, I think it would make it easier to make the leap into the abstract when required for other applications. And on top of this, it would make it much easier for the majority who only ever need to use mathematics as a tool.

            Depends.

            Did Jane take an apple from the only source of apples stated in the question; Johnny? If so then 2.

            Did Jane take one apple from a source not stated in the question. If so then 3.

            Has Jonny eaten any of his apples? If so then |3-n| where n is the number of apples Johnny has eaten.

          I would have certainly loved it if they showed me the actual problem and then solve it with math, instead of showing how to solve abstract, non-real-world problems in math using a bunch of complicated theorems that you just have to memorize (I know they can be solved, but you still have to memorize them for when you need to use them).

              Because there is no need to pluralize the word. Math is short for “mathematics” so writing “maths” just makes you look stupid.

              Ultimately it’s the same reason why you don’t say “admins” for administrator or detoxs for detoxification.

              Do you say flus? No you say flu because it’s the shortened version of influenza.

                Maths is short for mathematics, and neither is plural. Math, maths, and mathematics are all equally correct. I love when Americans tell people they look stupid because they don’t do something the way Americans do it.

        The biggest thing I learned from math was training yourself to think and problem solve. To always want to learn the next level of whatever you were learning, whether it’s math English or whatever.

        I don’t think I’ve ever used much math knowledge in my life … but it gave me the ability and enthusiasm of wanting to always want to solve a problem no matter how complex it was.

      I think it’s because some types of math are kind of all or nothing, either you know it or you don’t. If you recall half of what you learned in history you have some usable knowledge.

      I have not use trigonometry since I passed high school trigonometry.

          Without learning about how the trigonometric relationships of a throw relate to the physics of it, I don’t think a person that sees no value in knowing trig, sin and cos would change their mind.

        I like to view things with quantum physics in mind. “That’s weird and counter-intuitive…”, “I guess it’s meant to be that way.”

        Obviously it doesn’t apply to everything, and often your gut feeling is probably right. But the philosophy helps in keeping an open mind.

        With trigonometry, you don’t use it directly, but AC electricity and radio waves (eg WiFi or your phone) extensively rely on it.

      You use it, but it’s all preprogrammed into the software you use, so you can focus on the bigger problems.

      It’s a bit like how microprocessors are designed modularly using programming language. No one physically lays out a transistor on a 7nm die, that’s all dictated by code, where at the higher levels you just see “memory block” and “arithmetic block” or whatever.

      Finite Element Analysis is some funky shit, though, and often that’s done using bespoke software. You need to know the maths to build that, and it helps to have an understanding when interpreting the results. At least, it helps the person writing the report make a good report, though it’s not like anyone else will know if they get it wrong.

    This is dumb. Just because you don’t use logarithms doesn’t mean you never use deduction or process of elimination. Math is not solely about the numbers. The process is far more beneficial in many disciplines.

      The same vain is people arguing that schools should be teaching important things like budgeting, interest rates, taxes etc.

      These things a trivial if you have the maths skills. These things are also subject to change, the maths doesn’t.

      Worst of all, these things are all taught (in Scotland), the people complaining about school not teaching them weren’t paying attention.

    If you ever have to cut a bit of wood to act as a diagonal brace it’s pretty useful to whip out the old tan. So I’ve used this every time I built a gate.

    That’s four times in the last decade, so not exactly daily but I’m glad I knew how to do it or my gates would have sucked.
