Bet you feel a bit 500, 1 and 1000. :P
GOOD GRIEF - an intelligent joke :D :D :D
If IV is 4 and lX is 9, why isn't II 0?
I'm sure we all know that there are 10 kinds of people in the world. Those who use binary and those who don't.

The Romans did not have a zero.
It was the Arabs, apparently who did so.
The Arabs gave it to us, but the Indians (Mesopotamian claims? One for Ithoriel) were the inventors. They may also have been the first to use quadratic equations (for which, remembering my less than spectacular school mathematics experiences, I may never forgive them).

There are two kinds of people in the world. Those who can work from incomplete data .... :)

Does look like the Indians have that one.
At school quadratic equations were a mystery. Once I started to encounter them at work it turned out I was quite good with them. I still think that all school taught me was how to teach myself stuff! Which, to be fair, is a skill not to be sneezed at.

I know....and from Orcs! :d
Every person who claims maths is fun should be punched in the face!
Ummm ... maths is fun!
*Ducks hurridly*
Here's my favourite formula derivation:
Women require time and money
(w = t x m)
But time is money
(t=m: therefore w= m x m: w = m2)
We also know that money is the root of all evil
(m = sqrt(e): m2=e)
therefore
(w=e)
Women are evil
Mrs Westie says if she ever meets you, you better duck. ;D ;D ;D

See what I mean. How is that fun?
2 x wX (x-2y) = Z bananas ;D ;D ;D ;D ;D oh my sides! hilarious!

Somewhat off topic, but since the Tiny Goblin is taking his Maths national 5, I've rediscovered some old school maths tricks.
My own school maths was a mixture of aceing things that could be visualised, and being utterly bewildered by simple things that were explained in a non-visual style.
A great example of a befuddler was Imaginary numbers - "What's the square root of -1".
I tended to hit around 80% in exams, because about 4 / 5ths of the curriculum lent itself to visualisation.
Anyway, there's a recent video by Lindybeige on music teachers.
His simple concept applies well to the teaching of many other skills.

Maths are not fun but Math is fun (to resurrect a oft recurring theme).
I actually, really enjoyed MATHS .....Sorry, Bill ;)
I got a decent grade at that.
And what did I end up doing ?.........Pushing epoxy putty around.

I was fair at Calculuss (perhaps you know the subject as Fluxionss) and Differential Equationss. .
Stop bullying people from the USS. Some of them are quite pleasant...no, really, you'd be surprised....some of my best friends....

What constitutes a "better duck"? Longer bill? Greater wingspan? Cherry sauce? A bright blue sailor suit?
A better duck is one in which one achieves not being hit in the head.

I remember doing logarithms half a century ago.....Can't imagine those are still used for anything. I can only vaguely remember how to use them.
What about slide rules ?...I don't suppose they even exist, nowadays.

Why, when your mobile has a more powerful calculator installef than NASA had for the entire Apollo programme!
We have some on display in the museum...

Not used as they were in school Maths (Adding / Subtracting in place of long multiplication division), however they remain in many more advanced guises.
Examples:
1. Measurement over vast ranges: Richter or Decibel scales.
2. Big/small numbers (Scientific notation beloved of Professor Brian Cox and friends) "That has 32 zeroes after it".
3. Compound interest / growth.
4. Graphing trends where growth is exponential.
5. Atomic decay.
6. In everyday language: "Eight digit transfer fee".

Techno Logie ;) has progressed SO far.....(Too far ?)
I believe the first 'computer' that Von & I owned....(It was just a word processor, in truth)....Had more processing power than Voyager 1. The then
height of computer sophistication.
The main frame computer, that Von worked 'with', decades ago, took up a room the size of two tennis courts....and was eventually sold for scrap....after originally costing more than a million quid....THEN !
This piece of poop that I'm typing on, makes THAT 'computer' look like a giant abacus. ;)

First computer I used had programs typed onto punch cards.
They had to be given to computer services and they ran the program. Output was on big sheets of fanfold paper.

Well mine used paper tape !
My first encounter with computers was filling out Data Prep sheets for the operators to transcribe onto punch cards (great for shopping lists!) and I then had to authorise the run by putting my security code, which was on punch tape, into the tape reader.
... I feel so old!!
Muh old slipstick with muh new SpaceCorp game:

Warp factors are also logarithmic (I think)
Sinclair-Timex Z8? or, maybe, Trash-80
Learned on punched paper tape - cards made debugging much easier (unless you dropped the whole box on the floor!).
A maths teacher told us an engineer was a man (this was in the 70s, remember) who responded to the question "What is two plus two?" by pulling out a slide rule, fiddling for a minute, and announcing it was approximately 3.984.
I was told the History students' reply to the professor's good morning was good morning professor.
The Sociology students' reply would be a mute and confrontational silence.
The Engineering students' response was to write down good morning.

In a similar vein:
In interviews, three "numerical professionals" are asked the simple question: what does two plus two equal?
The mathematician answers, "Four."
"Just four?" replies the interviewer.
"Yes," replies the engineer, "two plus two equals four."
"Four," replies the statistician.
"Just four?" replies the interviewer.
"Yes, four, but with a 10% confidence interval!"
Finally, before saying anything, the accountant walks around the room, closes the blinds, locks the door, looks behind the filing cabinets and under the desk before answering, "Well, that would depend: what would you like it to be?!"
The professor turns to a rather prudish female student and asks,"What part of the human body increases to 10 times it's normal size when excited?"
The student responds,"That's disgusting! I don't have to answer that question!"
The professor says, "I've three things to say to you, young lady... first, you didn't do your assignment on the pupil of the eye; second, you have a dirty mind and third, marriage will be a huge disappointment!"

There was a time when I could read an 80 column card such as that shown above by just looking at the pattern of holes.
An engineer, a physicist, and a mathematician are shown a pasture with a herd of sheep, and told to put them inside the smallest possible amount of fence.
The engineer is first. He herds the sheep into a circle and then puts the fence around them, declaring, "A circle will use the least fence for a given area, so this is the best solution."
The physicist is next. He creates a circular fence of infinite radius around the sheep, and then draws the fence tight around the herd, declaring, "This will give the smallest circular fence around the herd."
The mathematician is last. After giving the problem a little thought, he puts a small fence around himself and then declares, "I define myself to be on the outside."
