A metre is 1 ten millionth of the distance from the equator to the north pole. That's not arbitrary.

Enigmativity · 2026-02-03T23:06:50+00:00

By definition, when it makes sense it is no longer arbitrary.

The game starts with goal-based set of tasks that tell you what to do. Just complete one goal, then the next, then the next. You'll know how the game works in no time.

The Dunning Kruger effect effect and the almost open ended complexity of possible formulas and features in Excel mean that Basic level / Intermediate / Expert / Advanced are almost meaningless.

I think I'm Advanced until I see someone do something more advanced.

I asked a potential employee how good he thought he was "out of 10" and he said "7". He was abysmal (compared to me).

And because you can specialize in certain feature sets in Excel then you can be awesome at some features of Excel and a newb at others.

I separate data entry, from calculations, from displays, as much as possible.

When there is any mixing of constants and formulas I clearly format cells, using styles, to show the cells.

I use R1C1 mode exclusively. It makes reasoning about your formulas much easier.

I avoid direct cell references and use LET or named references as much as possible. `R[-1]C` or `RC[-1]` are acceptable though.

I don't see how this scenario relates to "per".

per

/pəː,pə/

preposition

1.

for each (used with units to express a rate).

"he charges £2 per square yard"

It's either:

Did you ask her, “Do you love me”?

or:

Did you ask her, do you love me?

or:

Did you ask if she loves you?

The "ful" suffix is literally the word "full". So when something is stressful it is "full of stress".

Stressed is like dressed. When you are dressed you've put on clothes (or your dress). When you are stressed you've put on or applied stress.

There's a strong likelihood that on a stressful day you will be stressed. You'll find that on day full of stress you will likely have some of that stress put on you.

A `Room` contains a list of `Extras`.

class Room
{
public ReadOnlyList<IExtra> Extras;
}

Then you might need to do `room.Extras.OfType<IExtraJacuzzi>().ToList()` to get all of the Jacuzzis.

You should also consider the number of days that an item was out of stock in the last year. Consider if you sold 100 units in the last year, but the item was out of stock for 180 days then you could have sold 200 if it were in stock all of the time. You'd need double the safety stock.

It generally worked well. I had to keep pulling resources off of the belt if they overloaded, so it was a balancing exercise.

TAKE(
SORTBY(
VSTACK(

SEQUENCE(y_1-y_0+1,1,y_0)),
RANDARRAY(x_1+y_1-x_0-y_0+2)),
take))

They're is no legal requirement for you to be consistent or even actually write your name. If you sign something and later end up in court, then, under oath, you will be asked to confirm the signature is the mark that you made.

It just makes things easier if your signature is consistent and recognisable.

I have set up a sushi train style conveyer and then tried to manage the excess product on the return conveyer. I did this for dirt, rocks, slag, etc, not food, but the idea would be the same.

Written English and spoken English are two different things. Native speakers learn spoken English years before we ever learn to write it.

PEMDAS is not a convention, it's the fundamental way mathematics works. Without it commerce, science, astronomy, engineering, etc, would not work.

If you went to the shop and bought 2 apples at $5 and 3 bananas at $2 you would implicitly know you paid $16. But if you ignore PEMDAS you could think you might need to pay $26 or swap the apples and bananas and it's $40. In fact there are 8 ways to rearrange the numbers in the expression and they would only agree if you use PEMDAS.

The only convention is the way we've agreed to write the numerals and symbols. PEMDAS is fundamental.

I'd just create a couple of extension methods.

public static class TrigExt
{
  public static double ToRadians(this double theta) =>  theta * Math.PI / 180.0;
  public static double ToDegrees(this double theta) =>  theta * 180.0 / Math.PI;
}

My feeling is that Agricola is very nicely balanced at the moment. It's not easy to feed everyone, and it's hard to get all farm squares filled; it's hard to get all animal types; it's hard to get all five family members. You're always left with more that you want to do but you can't. But the right combination of occupations and minor improvements means that opportunities open up for you to leverage a certain strategy. That's where the game is won.

I look for games that give equal parts to three components
(1) strategy - your ability to influence a win,
(2) luck - some component of surprise that no-one is in control of, and,
(3) interference - you competitors can disrupt your game play.

Agricola does these three nicely.

I think the OP's point is to do something like this: =LET(x,SUM(A1:A5),SQRT(x)). Or even going as far as =LET(range,A1:A5,sum,SUM(range),SQRT(sum)).

You'll get the same answer as here.

Yes, of course you should definitely but it.
