                  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.
