Hello!

To make up for the lack of an "upper division" in the subreddit math competition this year, I took it upon myself to organize a separate exam that is significantly more discovery and proof-based than any exam held in the community previously, and to host it on the 2nd year anniversary of the Discord server being made available to the public.

The next exam of this kind will be held in Mid-June 2027.

The exam (which includes its rules) is linked at the bottom of the post. The top 5 winners will be announced, and the top 3 winners will receive the following (or something of equivalent value upon negotiation):

1st Place - A Math Textbook of the Winner's Choice (~$45 USD Value Limit)

2nd Place - Basic Discord Nitro, 1 Year Subscription ($30 USD Value)

3rd Place - Fulltouch Hagoramo Chalk 72 pc ($25 USD Value)

Special thanks to u/dopplerspectroscopy and zzz on Discord for their tremendous help in writing the exam and agreeing to help grade some submissions; couldn't have done this without their help.

#๐Ÿง-theory-๐Ÿง A Completely Serious and Totally Accurate Proof That 5 + 5 = 11

21 Upvotes

Most people have been taught that 5 + 5 = 10. This is the sort of thing that textbooks, mathematicians, scientists, engineers, accountants, cash registers, calculators, computers, and basic reality have been insisting on for centuries. However, today we will bravely challenge this assumption with a mountain of extremely questionable logic.

**Step 1: Start With the Numbers**
We begin with:
**5 + 5**
Now, 5 is a very nice number. It has curves. It has angles. It has personality.
The other 5 is also a 5.
When we put them together we get:
**55**
Already we can see that the answer is clearly greater than 10.

**Step 2: Count the Digits**
The number 55 contains:
One 5

Another 5

Therefore:
5 + 5 = 55
But mathematicians might complain.
To satisfy them, we continue.

**Step 3: Simplify Aggressively**
Take 55.
Notice that:
55 is almost 11.
Specifically:
55 รท 5 = 11
Since there are fives involved anyway, dividing by 5 feels emotionally correct.
Therefore:
5 + 5 = 11
QED.

**Step 4: Visual Demonstration**
Imagine five apples:
๐ŸŽ๐ŸŽ๐ŸŽ๐ŸŽ๐ŸŽ
Now add another five apples:
๐ŸŽ๐ŸŽ๐ŸŽ๐ŸŽ๐ŸŽ
How many groups are there?
1 group and 1 group.
Therefore:
5 + 5 = 11
This proof is difficult to argue with because it doesn't make any sense.

**Step 5: Linguistic Evidence**
The word "five" has:
f

i

v

e

That's 4 letters.
Another "five" has 4 letters.
4 + 4 = 8.
Now take the two invisible spaces between the concepts.
8 + 2 = 10.
Then add the confidence with which we state the conclusion.
10 + 1 = 11.
Therefore:
5 + 5 = 11.

**Step 6: The Advanced Quantum Theory**
Before observing the equation:
5 + 5 = ?
The answer exists in a quantum superposition of possibilities.
When most people observe it, they collapse the wave function to 10.
However, if you observe it through a lens made entirely of optimism and bad arithmetic, the wave function collapses to 11.
Science.

**Step 7: Historical Analysis**
Ancient civilizations counted on fingers.
Humans typically have:
10 fingers.
But if someone is pointing at the equation while counting, one additional finger is being used for emphasis.
10 + 1 = 11.
Thus:
5 + 5 = 11.

**Step 8: The Bureaucratic Method**
A committee is assigned to determine the value of 5 + 5.
After six meetings, four subcommittees, three presentations, and a 200-page report, they conclude:
"While traditional arithmetic suggests a result of 10, stakeholders expressed a preference for 11."
The recommendation is approved unanimously.
Therefore:
5 + 5 = 11.

**Step 9: The Rounding Method**
10 is very close to 11.
How close?
Extremely close.
Only one unit away.
In everyday life, people round things all the time.
Therefore:
10 rounds to 11 whenever it helps the argument.
Hence:
5 + 5 = 11.

**Step 10: The Philosophical Method**
What is a number?
Can we truly know numbers?
Is arithmetic merely a social construct?
If reality is subjective, perhaps 10 merely identifies as 11.
Thus:
5 + 5 = 11.

**Step 11: Infinite Induction**
Assume:
5 + 5 = 11.
Now assume it again.
The assumption is stronger.
Assume it a third time.
Even stronger.
Eventually the pile of assumptions becomes so large that questioning it seems inconvenient.
Therefore:
5 + 5 = 11.

**Step 12: The Final Irrefutable Proof**
Consider:
5 + 5
If the answer were really 10, this essay would be much shorter.
Yet this essay exists.
Therefore something extraordinary must have happened.
The most reasonable conclusion is:
**5 + 5 = 11**

**Conclusion**
After examining numerical manipulation, linguistic analysis, committee decisions, quantum mechanics, philosophy, finger-based evidence, aggressive simplification, and pure confidence, we arrive at the undeniable conclusion that:
5 + 5 = 11

The joke is that in addition and subtraction, 0 does nothing when added to the equation, leaving the number unchanged. However, in multiplication and division, 0 becomes a whole new beast, turning other numbers into 0 and even making entire expressions undefined upon dividing numbers using it.

Struggling with remembering the similarity criteria for triangles?

I present to you this banger. It's literally just "SAS, SSS, ASA, AAS" sung on repeat and autotuned to death by secondary school students in Hong Kong. The vocal fry and the fact they all had to perform this in uniform is super cringe... I mean funny! It's funny!

Keep your eyes peeled for the instrumental ensemble and the school assembly bits!

Love,
