Where does this math come from?

I guess the 21 being equivalent to 100 years is just an assumption

it’s a generally accepted assumption in many post-Tolkien fantasy works.

Nah, it checks out. I ran the numbers myself and I got 15.33, which is roughly 15. This, of course, assumes the age of adulthood is 21 for humans and 100 for elves, and we don’t really have a reason to doubt those numbers.

Why would we assume that you have to be 21 years old or the equivalent to drink alcohol in a medieval fantasy world?

There are still many parts of the modern world that allow 16 year olds to drink.

And even in the medieval time period of Europe, pretty much everyone would drink alcohol because it was cleaner than water, although younger people would tend to drink “small beers” that had very light alcohol.

My assumption would be that in this time frame, if the bartender judged you competent and capable of drinking, they would sell you alcohol.

If they didn’t, they wouldn’t, and the only consequence would be that you’re on your own in dealing with the effects of alcohol on you.

The dwarf is in a hoodie and holding a phone. Why do you think this is medieval fantasy?

because of the background and helmet, and the elfs clothing.

Those helmets were never worn outside of ceremonies, and those clothes are more victorian than medieval. And while the background does look olden style, there’s no reason a place can’t still look like that in the modern day.

There’s more to say this isn’t medieval than to say that it is.

In D&D, the standard assumption is that elves mature just as fast as humans, but they are culturally treated as children until around hundred or just a bit higher. But I’ve started developing a campaign setting where elves really are the equivalent of kids until that age, and all the implications of that. One of which is that, if humans attended school alongside elven kids, they’re going to lose their reputation of mystique and wisdom— they’re going to be viewed as kinda slow and dimwitted, as the humans graduate through the grades and the elevens get held back a decade or so.

Solving percents. I use this to predict gross and net of my paychecks when I do my budget.

Net               X
------    =    ------
Gross            100


(GrossX) = (Net × 100)

GrossX ÷ (Net × 100) = X

Example;

200             X
------    =   -------
250            100

Step A
200 × 100 = 20000

Now 250X = 20000

Step B
20000÷250=80

Therefore X=80
Also expressed as 80% of 250 = 200.

It’s also kinda handy when figuring out sales and stuff at the store, sometimes.

Hot 73 yo jailbait

This is the elFBI, open up!

Which kinda makes the math meaningless cause 73 < 100 requires no calculation.

Gennerelly accepted where ?

if 100 is the age of adulthood then it is equivalent to 18 in human years

only if you assume the drinking age is 21 or the equivalent. An assumption that is true for a small percentage of population of the world for a small fraction of human history

In the USA probably because it’s their drinking age

I get the 21 , but I’m not clear about the 100.
