When does one plus one equal three?
I have a mathematical proof for you:
Start with the following simple equation: $$a = b$$ (step 1) Multiply both sides by $b$: $$ab = b^2$$ (step 2) Subtract $a^2$ from both sides and factorize: $$ab - a^2 = b^2 - a^2$$ (step 3) $$a(b-a) = (b+a)(b-a)$$ (step 4) Simplify and add 1 to both sides: $$a = b + a$$ (step 5) $$a + 1 = b + a + 1$$ Now since $a = b$ (the starting point of this proof), we can write this as: $$a + 1 = 2a + 1$$ And in the case where $a = 1$, we have: $$1 + 1 = 2 + 1$$ So, therefore, $$1 + 1 = 3$$
Well, 1 + 1 has always equaled 3 :D
You see long ago, when the very first few math geniuses got together to come up with basic rules, they gave it lots of thought and settled on what's taught today.
But you see, numbers don't truly exist, they're a concept created by the human mind, and because our mind has created and developed them for years, and they are all in our head, we can merely change them.
So if you think 1 + 1 = 3, who cares if teachers and professionals say you're wrong! You are correct! Never forget that kids ;D Don't stop imagining! :D
