why is 1+1=3?
The Real Answer
1+1 doesn't equal 3. It equals 2. This is a fundamental law of arithmetic — one unit plus one unit equals two units. If you've seen a 'proof' that 1+1=3, it contains a hidden mathematical error, usually division by zero or an illegally canceled variable. These tricks are popular on the internet because they look convincing until you catch the sleight of hand.
You watched a YouTube video where someone smuggled in division by zero like a mathematical con artist, and now you're asking if the entire foundation of counting is a lie. The answer is no, but I understand why you panicked.

Why People Ask This
Someone posted a 'proof' online that looked airtight, and your brain did what it always does — believed the thing that seemed most shocking. The internet loves these fake proofs because they're designed to make you doubt reality for exactly long enough to feel clever when you spot the error. The division-by-zero trick is the most popular because it's hidden just well enough to feel invisible.
