It really bugs me that someone highlighted and circled this as if they found this ironic error when it was written as a joke headline in the first place and it went clear over their head. The equivalent of red circles and arrows on thumbnails
I see what you're getting at but the issue isn't really the assumed multiplication symbol and it's priority. It's the fact that when there is implicit multiplication present in an algebraic expression, and really best practice for any math above algebra, you should never use the '÷' symbol. You need to represent the division as a numerator and denominator which gets rid of any ambiguity since the problem will explicitly show whether (2+2) is modifying the numerator or denominator. Honestly after 7th grade I can't say I ever saw a '÷' being used and I guess this is why.
That said, I'll die on a hill that this is 16.
Ah sorry just realized what you were saying. I've never been taught that. Maybe it's just a difference in teaching styles, but it shouldn't be since it can actually change the outcome. The way I was always taught was if you see a number butted up against an expression in parentheses you assume there is a multiplication symbol there.
So you were taught that 2(2+2) == (2(2+2))
I was taught 2(2+2)==2*(2+2)
Interesting difference though because again, assuming invisible parentheses can really change up how a problem is done.
Edit: looks like theshatterstone54's comment assumed a multiplication symbol as well.
Not quite. It's true you resolve what's inside the parentheses first, giving you. 8÷2(4) or 8÷2x4.
Now this is what gets most people. Even though Multiplication technically comes before Division the Acronym PEMDAS, that's really just to make it sound correct phonetically. Really they have equal priority in the order of operations and the appropriate way to resolve the problem is to work from left to right solving each multiplication or division sign as you encounter them. Giving you 16. Same for addition and subtraction.
So basically the true order of operations is:
- Work left to right solving anything inside parentheses
- Work left to right solving any exponentials
- Work left to right solving any multiplication or division
- Work left to right solving any addition or subtraction

8÷2(2+2) comes out to 16, not 1.
Saw it posted on Instagram or Facebook or somewhere and all of the top comments were saying 1. Any comment saying 16 had tons of comments ironically telling that person to go back to first grade and calling them stupid.
I'm finding the opposite actually. Tried it months ago for basic python scripts and it was garbage. Recently started a project where I needed some c++ scripts to flash into an avr microcontroller and it's been killing it. To be fair I did a decent amount of code myself and also knew exactly what I wanted the program to do. But it has been really good about cleaning up my code, keeping the code consistent through multiple iterations, and understanding my explanations. It teaches me new functions that I didn't know existed which make the code better and faster. Also, when I was designing the circuit, I could describe what I needed a component to do and it would give me whole lists of, for example, possible types of 5volt voltage regulators and the differences between them.
I equate it to having a coworker rather than an employee. I can't really just tell it to do stuff and it'll spit out a perfect script. I need to work with it to make sure it understands my requirements and realizes it's errors. The biggest advantage is this coworker has encyclopedic knowledge of electrical components and c++.
Definitely. I posted on r/DIY with a picture of a ceiling I was patching in my house. My house is old and I wasn't familiar with the construction style of my ceiling. I was already well into the job: light fixture removed, ceiling joists exposed, new sheetrock going up. But I wanted to know what the old construction material was and if it was known for being hazardous. So I posted a picture of a chunk from the ceiling with my clearly-already-very-much-started project in the back. Within 15 minutes a mod removed it because "no asking the community how to get started with a project." I try and fight it but they weren't having it.
Over the next week I watched so many posts get very popular on the sub with just a picture of a floor, or wall, or bathroom with a title like "thinking of adding outlets to this wall but don't know how to start. Help."
Here's something you need to consider though. We need a well trained Navy and Coast Guard. It's kind of a necessity that those guys know how to perform water rescues and can perform them well. And it's for that reason that they actually use events like this for training when they can. Obviously this is extraordinarily rare, so typically they stage trainings for deep water recoveries instead. This is more useful, more real training than the latter option. Likely no one is going to need to pay for the recovery because it's built into the Navy and Coast Guards budgets set aside for training that would have otherwise paid for a staged recovery. Only this time, they were able to use an actual disaster as a training opportunity. They likely knew, or we're at least confident that the sub imploded on that Sunday but still spent 4 days on the recovery effort partly to train and partly to get additional evidence to confirm their suspicions.
ho ho hoooooo boy. My company forced some of us to choose what schedule we wanted coming back to the office. They sorted this by job titles. I just so happened to be one of the few jobs they were forcing to come back. I work in IT and I work with developers and project managers mostly in my day-to-day. I love WFH and I'm really not a fan of driving 20 minutes each way out of my way to go to an office and do things that I can do from home just fine. But the board is a bunch of super old dudes who demand that we do it because of the company's traditional values and culture. So naturally I chose the lowest requirement of days in the office that they offered. Get this, though. When it was first pitched to us that we were being forced to come back despite most of our peers getting to WFH, they said it was to encourage in-person collaboration. Motherfucker, the people I collaborate with daily (the aforementioned PMs and Devs) didn't come back! They are all WFH! I don't collaborate with a single person in the office ever!!
And to add to all this, the board has now been giving out hints that they aren't happy with how many of us chose the lowest number of in-office days for hybrid schedules, they expected us all to voluntarily opt for higher number of days, and they want us all to strive to come in more. Again, god dammit, why would you give us a choice of days if you already had a target in mind of what you'd prefer us to do?? Just make that target a requirement and deal with all of your employees hating you for it. Seeing the numbers of how many people don't want to be in the office should make you realize that you fucked up making us come back and be more lenient, not force us with an iron hand further into a schedule we all opted to avoid. Fucking insanity.
Thank god you asked this. It's been like pulling teeth trying to get google to show anything on any fediverse instance
Finally no dashes or underscores!
I lost my dad to cancer about two week before last Christmas. And my birthday is a few days after Christmas as well. I'll be damned if I ever feel like celebrating Christmas or my birthday ever again
