I feel like I am getting trolled

Isn't 17 the actual right answer?

So it's just an unfunny meme?

[–] NewDark@lemmings.world 102 points 1 month ago (1 children)

I think it's meant to play with your expectations. Normally someone's take being posted is to show them being confidently stupid, otherwise it isn't as interesting and doesn't go viral.However, because we're primed to view it from that lens, we feel crazy to think we're doing the math correctly and getting the "wrong answer" from what we assume is the "confident dipshit".

There's layers beyond the superficial.

I fell for it. It's crazy to think how heavily I've been trained to believe everything I see is wrong in the most embarrassing and laughable way possible. That's pretty depressing if you think about it.

As most memes are.

Not even a meme.

Some people insist there's no "correct" order for the basic arithmetic operations. And worse, some people insist the correct order is parenthesis first, then left to right.

Both of those sets of people are wrong.

Hopefully you can see where their confusion might come from, though. PEMDAS is more P-E-MD-AS. If you have a bunch of unparenthesized addition and subtraction, left to right is correct. A lot of like, firstgrader math problems are just basic problems that are usually left to right (but should have some extras to highlight PEMDAS somewhere I'd hope).

So they're mostly telling you they only remember as much math as a small child that barely passed math exercizes.

If you have a bunch of unparenthesized addition and subtraction, left to right doesn't matter.

1 + 2 + 3 = 3 + 2 + 1

True, but as with many things, something has to be the rule for processing it. For many teachers as I've heard, order of appearance is 'the rule' when commutative properties apply. ... at least until algebra demands simplification, but that's a different topic.

Well the rule is: any order goes. Summation is commutative.

[–] MotoAsh@piefed.social 5 points 1 month ago* (last edited 1 month ago)

No, you completely misunderstood my point. My point is not to describe all valid interpretations of the commutative property, but the one most slow kids will hear.

OFC the actual rule is the order doesn't matter, but kids that don't pick up on the nuance of the commutative property will still remember, "order of appearance is fine".

PE(MD)(AS)

Now just remember to account for those parentheses first...

Huh I just remembered the orders of arithmetic but parentheses trump all so do them first (I use them in even the calculator app). Mean I assume that's that that says but never learned that acronym is all. Now figuring out categories of words;really does my noodle in sometimes. Cause some words can be either depending on context. Math when it's written out has (mostly) the same answer. I say mostly because somewhere in the back of my brain there are some scenarios where something more complicated than straight arithmetic can come out oddly but written as such should come out the same.

I mean, arithmetic order is just convention, not a mathematical truth. But that convention works in the way we know, yes, because that's what's.. well.. convention

There is no answer. Because there is no question.

I know the solution
