Is BODMAS a recent thing ie last 40 years or so .. or has it always been around?

I don't remember learning it at schools - and I remember using FAR more brackets all over the place which guided order of actions....

Brackets first and foremost should be used say in the 2+5x3 not to be 17 you should say

(2+5)x3 to make 21

brackets clearly show what the person writing wants to have happen

I'm 61 and learned it at school although then it wasn't called BODMAS, it was the order of operations. I did A level Maths and I remember using all 3 different types of brackets in specific ways, or perhaps that had already happened at O level.

I only encountered BODMAS when my children were at school.

School and a level maths in the 90s and never heard of bidmas or bodmas but we were taught the order to solve equations in

57 and never heard of it until about 7 years ago. I have Maths O-level.

Obviously if you know order of operations which you may or may not have been taught an acronym such as BODMAS for.

It sounds like you know about order of operations but maybe not the acronym.

Not to be an asshole or anything, but 5 x 5 is 25, not 15

Learned it at school I’m 57.

Not learned at school. I’m 65

Secondary school, 1980s.

Brackets Orders Division Multiplication Addition Subtraction - but we were taught to convert into bracketed clauses to embed the concept, so if faced with (2 x 23) x 32 / 10, we'd break it down into (2(2x2x2)) = (2x16) = 32 x (3x3) = 32 x 9 and divide that by 10 until we could confidently/reliably/automatically do it by the end of the lesson.

SOCAHTOA was probably done at the beginning of Y10.

The entire class passed, so I don't think they did too badly.

Oh, yes, sorry - I had just woken up from a nap, I promise 😊

Even though my actual multiplication was off there as pointed out by another poster 😄

similar here, I’m 68 and never learned anything called Bidmas/Bodmas but can vaguely remember rules such as “ brackets first” and “ multiply before adding”

Yes I noticed that but didn’t feel it was relevant.

I'm 52 and covered did it at school.

Im early 40s. I had it although other people my age don’t recall it. We def had it though, they just forgot 😂 I’ve also heard it called PEDMAS before too (possibly American way to say it)

Mid 40s, didn’t learn this at school and only discovered it in adulthood (when a family member was doing a college course!). I’m sure it’s been around for eons and may even have been part of the curriculum, but we definitely weren’t taught it - it would’ve made my maths experience infinitely easier!

I learnt it, except I think we called it BIDMAS… I’m in my late 30s.

You may not have been taught the acronym but you can't do algebra without knowing order of operations.

What is 3y^2 when y=5?
(Answer is 75 as you do the index then the multiplication, not 225).

My parents learnt BODMAS (and soh cah toa) overseas and they are now mid-late 70s.
My DC now learn it as BIDMAS to include integers.

I remember it. I’m 52 and it was BIDMAS.

I have no memory of it at all. I am 61,

I definitely remember learning it at school when I was about 12/13. I'm now 61.

What do you think
2 + 3 x 5 is?

I learnt it at school (I'm 42) but I always drop extra brackets in just to make sure, especially in Excel!
