        20/50, about average for me :/

        Also to be fair! I did the math! I just did it in the wrong order and got 24

          I had to remember the order of operations, managed the correct answer after a shameful number of minutes 😬 BEDMAS helps

            I really hate that that’s even a thing. Logically, my brain wants to do it in the order that it’s shown in. Doing it any other way just feels unnatural. Like building a roof before building the house

              Helps to isolate the problem by putting brackets round anything that you KNOW needs to be done separately.

                Doesn’t help much if I don’t KNOW what needs to be done separately.

                  PEMDAS

                  parenthesis, exponents, multiplication, division, addition, subtraction.

                  That’s how I remember it.

                    I learned BOMDAS

                    brackets, of, multiplication, division, addition, subtraction

                    The next year I learned BODMAS instead, which was initially confusing but introduced the idea that the exact order can be a bit variable, as long as you do the multiplication/division bits first.

            I had the order of operations with no problems, but somehow managed to calculate 18-12 = 4 which really messed me up.

            I am good at maths in theory, but tend to muddle up calculations in my head. I really need to be able to pin the numbers down on paper, in my head it’s like they wriggle around on me.

              Similar with spelling for me. Can’t do it out loud without at least air writing it with a finger, and paper is better. Odd mental blank spot.
