says person who has no evidence whatsoever

Yes, because I finished third grade in primary school. Do you also expect evidence of gravity?

And the questions I did ask you didn’t answer anyway

Go back and read the comments again. I know they’re getting lengthy, but I’m sure if you put your mind to it, you can find the answers.

Which proved you were wrong

Yeah, if you ignore what the text says and just assume it does what you want, then sure, it proves me wrong. However, if you actually read the letters on the screenshot, you’ll find that it does not, in fact, prove me wrong, it does the opposite.

Well, here you go proving you have a severe comprehension problem anyway… 😂

Oh wow, so you’re also incapable of scrolling down to the sources part of the article…?

Yep, gives the same result, but does not say that the number and it’s inverse are the same thing 😂

Yeah, speaking of reading comprehension - I never said anything like that. I said that, in terms of the order of operations, addition/subtraction and multiplication/division are equal, because they can be inverted (subtraction into addition of negative numbers, division into multiplication of fractions) to achieve, as you observed, the exact same result. Which means that - if you ensure that children learn and understand that concept, you can skip subtraction and division from the mnemonics, because children will understand that - again, in terms of order of operations - division = multiplication, and subtraction = addition.

Which also wasn’t a Maths textbook

OK, how about this: let’s do what grown up mathematicians do: prove that what I linked to is wrong.

Which they never are (…) Nope, no-one thinks that

One more time: welcome to the Internet, I’m sure you’ll find many surprises here, but overall it’s a pretty great place.

Addition first for 9-3+2 is +(9+2)-3=+11-3=8 same correct answer as left to right, which is why the textbook teaches you to do it that way

I like how you’re doing exactly what I’m talking about while still saying I’m incorrect.

Which you’re demonstrated repeatedly that you don’t, and here we are

OK, sure, quote one example equation I did here that proves I’m not understanding these concepts. :)

Which is a totally valid thing to do, as is taught by the textbook

But is not reinforced by the mnemonic itself. Reading comprehension, remember?

Which is also a valid thing to do. That’s the whole point, it does not matter which order you do addition and subtraction 😂

I’m glad I was able to explain this to you. You go ahead and pretend like you’re explaining it to me, I’m just happy you finally managed to understand that.

And when they do calculate the addition first, they get an answer of 8, as I just proved a few comments back 😂 Add all the positive numbers, then subtract the total of all the negative numbers. This is so not complicated, and yet you seem to have trouble understanding it

See above.

From an example of how 2+2 and 1+3 aren’t the same thing, even though they equal the same value, which you are now trying to avoid addressing because you know it proves you are wrong 😂

Why are you bringing 1 + 3 into the mix when the examples were 2 + 2 and 2 * 2? What are you trying to say here?

I’m starting to wonder if you do, given you think 2/2 is the same thing as 2x½ - one has a fraction, the other doesn’t, but you think they are the same thing 🙄

I’m going to ask you a couple of questions so you can research that and then pretend to explain them to me, like you did above:

  1. What is the result of 2 / 2?
  2. What is the result of 2 * ½?
  3. What is the reciprocal of 2?

says person not remembering that they brought it up to begin with… 😂

There’s no confusion from my side. I understand how brackets work and that was a perfectly valid use - for readability’s sake.

says person who thinks doing addition first for 9-3+2 is 4

Now you’re just inventing things I never said. That’s not nice.

Not for 2-2 they don’t. Go ahead and cite one. I’ll wait

It wasn’t 2 - 2, tho. Or did you fail to read that correctly too?

Which proves my point that you can do addition and subtraction in any order, given you just admitted that 2-2 and -2+2 give the same result 😂

Again, I’m glad you’re slowly getting to the point I was making. It’s weird how you’re still phrasing it like I was somehow wrong, but I’m just happy you learned something.

The exact same thing as an expression written without pronumerals 😂 I see you’re still not understanding how pronumerals work then

Considering that’s exactly what I did, how do you see that as me not understanding pronumerals? I’m asking out of sheer curiosity at this point.

and thus proving again that they can be done in any order 😂 It’s so hilarious watching you prove yourself wrong (…) [and the rest of the comment]

You’re so cute when you’re trying to turn this whole argument on its head after realising how silly your initial points were! <3
