Reply to comment by Twin_Spoons in ELI5 what is the benefit of a charter school vs regular public schools? How do they differ? by [deleted]
My moms a teacher, and she has gotten a few kids from charter schools.
They are almost always behind the regular curriculum, and they almost always have to be retaught things that other kids don’t need.
Now granted that may just be multiple bias being seen, but from my moms experiences, charter schools here suck educationally compared to public schools

Hey, I went to the shops today and bought 3 eggs and 2 loaves of bread. Eggs cost me $2 each and the bread was $5. In total I paid $16.
3 x 2 + 2 x 5 = 16
We do the multiplication first.
However, if we didn't, and we just worked from left to right, then this would happen:
3 x 2 + 2 x 5 = 40 (eggs then bread)
Or:
2 x 5 + 3 x 2 = 26 (bread then eggs)
It just doesn't matter what order I buy my eggs and bread if we do multiplication first.

1-2 minutes isn't too uncommon if it was a half with a small amount of fouls/interruptions. The first half of the Brazil vs Switzerland match is a good example of it, with only an extra added minute.

Reply to comment by Graega in ELI5 why we first multiply, then add by TheManNamedPeterPan
Why couldn’t you just write it 5 x 12 + 2 and solve it all left to right? Or just stick with parentheses as the operator. (5x12) + 2. Could math not be simplified in this way or would it fall apart with more complex equations?

Depends on the school, there isn't a blanket answer.

Reply to ELI5 Are cows constantly producing milk? by ms_myco
Man, nobody here with the answers.
Selective breeding for the last 10k years.
A heifer is an unbred female cow. Heifers do not produce milk. A dairy heifer is going to be a cow of a dairy breed, Jersey, Gurnsey, Holstein, there's a lot. Beef heifers are never the same breed as a dairy heifer even though they're functionally the same at that life stage.
Once a cow is bred it'll go in one of two directions. The beef cows only produce enough milk for their calves but all mammals produce milk with a supply/demand method (generally). The more milk a calf drinks, the more milk a cow produces. So until weaning begins supply slowly increases with the calf's appetite. For some things you might be able to get some excess milk even from a beef cow but nowhere near the quantities you get from a dairy cow.
When dairy cows have their calf they do generally get promptly removed from momma. But momma is still useless for milking at this point. She's not producing milk. She's producing colostrum. Colostrum is discarded by some farmers, milked and fed to the calf by other farmers. Either way it has to be milked from the cow. Milk production starts quickly, though, as colostrum is only ever at temporary thing. The calf is always removed because cows are on the farm to work and where a beef cow's job is to make meat (which they can do by making more cows) a dairy cow's job is to produce milk.
A dairy cow that has already had at least one calf and is due to have another will actually go dry shortly before she has the calf. Her glands are switching back to colostrum mode.
Dairy cows produce so much milk that their udders are gigantic compared to a beef cow's, even when both are lactating. They produce so much more milk than any single calf could ever drink. They also don't necessarily produce the sort of milk a farmer wants to feed to the calves. Calves drink fortified reconstituted milk (made from dried milk that's had a blend of nutrients added).
The reason why a cow's milk and their calf's needs don't necessarily line up is because of the selective breeding bit. We want cow's milk to taste a certain way. But we also want calves to get a certain sort of nutrition. The nutritional needs of a calf, particularly one you're raising for a specific purpose, is not going to give you the stereotypical flavor of milk, cheese, and yogurt you get in the store.
You take away the human element and yes, a dairy cow and calf could easily stay together and we'd still have plenty of milk. But there's no profit in producing milk. Farmers make pennies per gallon so in order to stay solvent they have to maximize production and quality. So the only time you're going to see a farm where they can keep the calves with dairy cow mommas is a farm that likely packs and sells the product themselves rather than selling it to a factory or brand.
Sauce: I grew up in a farming community for 20 years and visited dozens of mom and pop farms providing cow healthcare and saw the whole industry as seen through the eyes of farmers with less than 10,000 cows.

I used GOTO like candy in the early 80's with Microsoft BASIC! But otherwise, I've been coding professionally since 1996 and have used GOTO exactly once and that was last year actually, to jump to some error handling code in a particularly dense and multi-faceted set of conditionals. It seemed like the cleanest way to handle things, and it was within the same function of course so pretty reasonable.

Surprisingly, diving in hockey (especially high level hockey) really isn't a big issue. You'd be surprised how often it actually gets called.
Refs in hockey, unlike NBA and football/soccer, are pretty empowered to make the decision to call a diving penalty, as such you see far less of it than you might otherwise see.

It can also be used as a time wasting tactic. The assistant referees at this years World Cup seem to have cracked down on this by adding on much more additional time after the normal 90 minutes. There was 9 additional minutes in the 2nd half of the US-Iran match. That’s an enormous amount of time. It’s typically between 3-5 minutes of additional time.

Yes, its true, they all need breaks so sometimes you see this in play, where someone just takes a lot of time and everyone gets some water. But this is also, kinda a mutual waterbreak, to a degree.

Why do they do it: a penalty, even a free kick outside the penalty area, can be incredibly advantageous. Getting an opposing player a yellow, or red, card is also helpful.
Why is it allowed: the sport has been hesitant to allow too many pauses to check computers, we have definitely seen that happen this world cup so far. But, if a referee catches a player intentionally faking they have and will reprimand them by giving them a yellow, or red, card. Two yellows and they automatically get a red card and their team will be down a player for the rest of the game. That and they usually cant play, at least, the next game.
As we get more technology involved, it may be more difficult to get away with cheating, but then, new methods to cheat may then evolve as well.

Reply to comment by Specialist-Big2165 in ELI5 When selling an item in an auction, why set a minimum reserve amount if the bidders can’t see it. Why not just set the minimum bid at the lowest price you’d be willing to sell at? by lsarge442
You could also look at the 'completed listings' option on ebay that shows you what the winning bid price was for the same item.
I usually check for the completed listing value. If I feel the price is fair, I set my item to Buy It Now at that price , and require immediate payment.
Makes the sale quick and convenient. Otherwise you have to wait for the auction to end, and then sometimes days for the bidder to get around to making payment.

There are a lot of ways from having an already existing big door (but rarely used) so you can move things in.
Or windows.
Or some clever maneuvering, like multiple pivot points etc..
In most cases the homeowner should be keenly aware HOW to get something big in in the first place.
Worse case...sledgehammer.

We live in a racist and classist society and we're all marinating in it 24/7. You aren't exempt; everyone has absorbed racist and classist beliefs just by existing.
Until that changes, it's what we do when we learn about the racism and classism inherent in an idea or a phrase that defines us. Now that OP is aware that it's racist and classist, they can choose not to use it anymore and can "spread the knowledge" to others.

Hockey has a diving problem too.
NHL rule book.
64.1 Diving / Embellishment – Any player who blatantly dives, embellishes a fall or a reaction, or who feigns an injury shall be penalized with a minor penalty under this rule. A goalkeeper who deliberately initiates contact with an attacking player other than to establish position in the crease, or who otherwise acts to create the appearance of other than incidental contact with an attacking player, is subject to the assessment of a minor penalty for diving / embellishment. 64.2 Minor Penalty – A minor penalty shall be imposed on a player who attempts to draw a penalty by his actions (“diving / embellishment”).

I always assumed that, in addition to being a trick to try to get the other team in trouble, it was also a trick to get to sit down for a minute - soccer players run around A LOT.
I know it’s terrible, but I kind of like it. It’s the only real sport I can think of that incorporates drama class. Like, you can win by being good at soccer, but it also helps to be good at pretending, and everyone is in on the pretending what with the dumb little “healing spray” and all.

My 85" TV is roughly 45". That would be an incredibly large TV to not fit through a standard door.

Best Buy has a 100” tv for sale. The box for that is 62” tall, so it’ll still fit through the door.

The idea behind flopping is to (a) create a foul out of nothing, (b) turn a borderline foul into a called foul, or (c) make sure an actual foul is called. The first should be fined or otherwise penalized, it's cheating. The third is fine with me, sometimes you need to call attention to a foul.
The middle one is difficult to regulate. On the one hand, I wish players would play through more borderline calls. On the other hand, I can see why they try to turn them into fouls, and there's enough there that it's hard to fine or penalize them for it.

>the TVs in question don't appear to fold or come apart
No shit, but it would be helpful if you provided an example of the TV in question? Looks like their largest commercial screen of 97" is 'coming soon', it's just under 1.3M in height, I just measured a standard door@1.97M.
I'd guess they take the doors off or worst case, remove a window, like with a normal TV and whatever example you've seen LOOKS as though it's larger than the property's doorways, but in actual fact you're estimation of relative size is off.
