1 = 2
The equation of choice among math paradoxers and recreational mathematicians, who unspokenly derive much satisfaction in exposing students’ fallacious or illogical reasoning that leads to the contradictory result.

1 = 2
The person before made a mistake in their proof.
1. x = y
2. xy = y^2
3. xy - x^2 = y^2 - x^2
4. x(y - x) = (y + x)(y - x)
So far so good.
4.5. x = (y + x)(y - x)/(y - x)] is what they did to get to step 5, which says:
5. x = y + x
This is wrong though. since x = y, y -x = 0, and so you can't divide by y - x.
1. x = y
2. xy = y^2
3. xy - x^2 = y^2 - x^2
4. x(y - x) = (y + x)(y - x)
So far so good.

As proven, 1 = 2, thus 0 = 1, etc. And so for any number i, there is an equivalent j that is not equal to i.
This is further explained in the Identity Theft Theorem.

1 + 1 = 2
It has taken years for scientists to do all the studies to thus prove that 1 + 1 is actually 2. After a long and hard (lol, long and hard) test involving one apple, than adding another. The tests were proven that 1 + 1 is in fact, 2.

3 + 2 = 1
A mathematical statement most grades K–2 students would disqualify as being an equation, thus revealing their partial understanding of the meaning of an equals sign, which has different meanings.
1 + 2 + 3 = 1 × 2 × 3
The nontrivial solution to the equation a + b + c = a × b × c, where a, b, and c are positive integers—the sum and the product of three whole numbers are the same.
Besides 1 + 2 + 3 = 1 × 2 × 3, the numbers 1, 2, and 3 form the set of three integers such that each divides the sum of the other two, and their reciprocals show that the number 1 can be expressed as the sum of three unit fractions: 1 = 1/2 + 1/3 + 1/6.

murderhobo
In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.
The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.
