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.

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

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

PEMDAS
parenthesis, exponents, multiplication, division, addition, subtraction.
That’s how I remember it.

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.
