> How are "Employment", "Loans", "Starting a Family" and "Stock Market" each a singular topic???? especially when compared to things like "Debit Cards"?
What "Employment" covered:
Classification (W2, 1099, etc.)
Salary vs Hourly
Perks & Benefits (PTO, Retirement match, insurance, etc.)
Considerations (Stability/Raises/etc.)
Salary vs Gross via deductions
Job Stats (median income national/local, most in-demand, etc.)
And more
Also, it is a remedial course, so can't go to extreme & in-depth with many topics (some of these 18yr olds can't even multiply by 10).

Yes, I have done that. Now, how much they retain afterwards is on them.
I even had them make a spreadsheet that calculates how much Federal Income & FICA they would have to pay. I even included the SS cap and Medicare "bump".

Reply to eli5 how fast charging works for phones. by Phoenix_3222
Fast charging does damage battery health, this is why many switch to normal/slow charging once you hit 80%.
If you are the kind to have a new phone every 1-3 years, then it’s not gonna matter; but if you are planning to have it for like 6yrs, then only fast charge when needed.

Bigger sensor means more light capture. No increase in megapixel count would result in lower noise. Increase in megapixel count results in similar noise (smaller though) but higher detail.
Larger sensors also give more depth-of-field (even if aperture is the same).

If you are American then I assume you know about the mag stripe on the back. Think of chip cards as storing the same data as a mag stripe but it also changes the codes every use, and the previous codes can’t be used by your card again; this way even if someone gets that info, it’s useless. As for tap to pay (card or phone), it’s just a wireless version of the chip.

Yep, and tv since upgraded to 16x9. Hollywood movie have not, because they are wider, and it’d ruin that cinematic feel.
Well, certain IMAX movies/scenes are cropped to 16x9 from their originally taller former.

Reply to comment by GandalfSwagOff in ELI5: how can they spend our tax dollars but yet refund those tax dollars every year? by hktactical
Well, they know at the end.
A classic example would be if you take a take a deduction for auto-expenses or mileage, the government won’t know how much less to take if you don’t calculate the deduction at the end.
Or let’s say you don’t take the standard ~$13k deduction but instead want to do itemized, they have no way of knowing your itemized deductions unless we were to go full tilt with the government having a profile for every person and tracking every single transaction they make.
Or, you don’t need to contribute any more to Social Security once you hit a certain amount, but you have to contribute a higher % to Medicare once you hit a certain amount; if you have more than 1 job, how would either job know how much you are making in total (including any other sources of income)?
If US taxes were simplified, then yeah, having each worker file every year would not be needed.

Reply to ELI5: Why is it that, at some gas stations, it’s cheaper to pay with cash instead a credit card? by tgjj530
Besides charging interest on late payments, cash advances, etc., credit card companies / networks make money by charging the store/merchant a fee (usually a mix of a % and a fixed fee, something like 2.5% + 15¢); this is one reason as to why they can offer cash back/miles as rewards. Debit cards also have a fee, but a bit less.
This is also why American Express isn’t accepted everywhere, as they charge a higher fee.

Reply to comment by Oilfan94 in ELI5: Why do electric vehicles need a MPG measurement? I by WannaBelTGuy
It would make more sense to state what % battery loss is used per hour or city/highway driving, or total time you can drive for city/highway.
The Leaf advertising 121 MPG means nothing, as I don’t know how many “gallons” a full charge has. My car advertises like 36 MPG city, and with a 12gal tank I know I can drive ~430 miles.

Reply to comment by MacaroonElectronic68 in eli5; how does the stock exchange work? by dirtycumsock69420914
Just to note, not all stocks pay dividends. For instance, Apple does but Amazon does not.
homeboi808 t1_j28nx62 wrote
The stock exchange is where companies willing to publicly sell off ownership of their companies do such trades (they have to be approved of course, and follow a lot of regulations). In America the 2 largest ones are the New York Stock Exchange located on Wall Street, and the NASDAQ which is digital.
These pieces of ownership, shares, sometimes allow you to have voting rights as well as receive profits, dividends, which are in-line with the % of the company that you own. Now, not all shares come with either/both, so just do some research (you can just Google: “Does Apple stock pay dividends?”). You could cash out these dividends, but since it usually is a few pennies/bucks for most people, they instead choose to opt-in/enable a feature called Dividend Reinvestment Plan (DRIP), where they money is instead used to buy more shares of that company, that way you earn more shares and also earn more dividends, and this repeats and repeats (you could do this all manually especially since nowadays it is commission free and fractional shares can be bought; it used to be much more appealing before this, as now you could take the money and buy fractional shares in another company if you wish).
A broker is a person/app that handles the transactions (think Leonardo DiCaprio in Wolf of Wall Street); you yourself can’t just walk up to the NY Stock Exchange on Wall Street and do business). Historically brokers have charged commission fees but now most are free (they make money from offering other services, such as financial advising, they also require the money you wish to use to make purchases to be in their fund for them to invest in, rather than just charging your bank account).

There are multiple different color spaces that have different degrees of vibrance for RGB and in-between.
sRGB uses 256 shades per color. So while this totals >16M combos, if you want a shade of red to be 137.5, you’ll have to settle for 137 or 138.
Also, printers use ink, not light, and are using CMYK (K is for black, not used a lot in standard colors, moreso metallic and gold-ish). CMYK can go more vibrant for green but less so for blue/purple. It uses 0-100 for all 4, totaling 104M combos.
Printer calibration is a huge issue. My mother uses Walmart for Christmas photos and every time they look like crap. A huge benefit of Pantone is that print shops order Pantone books of swatches (stupid expensive) and they calibrate their printers are accurate, so if your digital file is using a specific Pantone color, then that is exactly was is getting printed.
Now, some shops give out their ICC profiles and you can download them it’ll show you what your image will look like from that printer. However, you are still looking at it from a digital screen emitting light and not a printed surface reflecting light.

Reply to comment by Godzarius in ELI5 why fraudsters like Anna Sorokin managed to deposit bad checks and immediately withdraw cash elsewhere without banks stopping it? by 6horrigoth
Sadly, we have elderly people who don’t even know how to power off their phones. Add onto the fact of all the people afraid of scams. I have an uncle who Carrie’s around his money in a ziploc bag so he can see if he is missing any cards.
I’m a high school teacher, I have students who don’t even know how to use a laptop. I had a student bring in her own MacBook and I surprise her by being able to right click.
But, we do have bank-to-bank transfers which are free & instant, but only if the receiver & sender banks support that platform. Zelle is the platform most used in the US (vast list of supported banks), but there are of course some that have their own platform they made and aren’t willing to ditch it.
You do have wire transfers, but they take longer to setup (verification), it takes a few days to go thru, and it has a small fee.
This is why Venmo, Square/CashApp, etc. are still around.

This is why most places don’t take checks, only cash or card. Usually only if you really trust the person do you accept checks; and that was her whole scam, to make people think she was trustworthy.

Also, the internet speed of where you are downloading the files from matter. Your internet speed is likely always higher than the places you are downloading from.

Reply to comment by Schnutzel in ELI5: are megapixels just resolution but for still images? by weakgutteddog27
For those wondering, most camera can record video in a much higher fps than their burst photo rate. This is usually because the video is lower resolution and has a lot more compression, this leads to the processor not needing to work as hard/long to take each frame.

Multiplication is just shorthand for repeat addition, as such the 2 values are linked together, you can imagine an invisible parenthesis.
1 + 2 x 3
= 1 + (3 + 3) , or 1 + (2 + 2 + 2)
= 7
1 + 5 x 10
The above is similar to saying you are adding $1 to a 5-pack of $10s (or a 10-pack of $5s), which equals $51 and not $60.
If you instead meant to have a 10 packs each containing both a $5 & $1, so $60 total, your expression should be:
(1 + 5) x 10

Reply to Eli5: Mortgage rates by sanevsnormal27
When you make the required monthly minimum payment, you are paying towards both the principal (loan amount) and the interest added.
At the beginning, the majority of the payment is going towards the interest and then the ratio slowly changes so that towards the end, it is the principal that is what most of the payment is for.
When the interest rates change, they look at how much principal is left and then redo the payment amount with the new percentage and years left. So, if you have $65,000 left and you've been paying for 5 years, then it's the same math as a $65,000 loan on a 25yr repayment. So look at how much principal is left on the loan and then the time left on the 30 years.
Now, your monthly payments are sometimes locked in until you hit a "trigger" where the monthly payments need to be adjusted. If it isn't adjusted, then you keep paying the same monthly but then have balloon payments or longer payoff length (more than 30 years).

Reply to comment by anujshr7 in eli5 why is 9 the last number? and why then we use 10 and repeat in sets of 10? by anujshr7
We didn’t always; many humans used to use “12” instead of 10, hence why times and calendars are all based off 12 (but still relating to hands, they counted each segment of the thumb, so 8 from the others fingers and 4 from the thumbs).

I showed a few videos of Caleb Hammer on YouTube, where he does financial audits on others. One was a married man where him and his wife combined made >$200k, yet he owed I think $40k in back taxes; another was a 24yr old entrepreneur who was living paycheck to paycheck (even after his father being his landlord and giving him a steal on rent).
