The shortest equation in mathematics is an inequality - Apparently.
The equation, named after the Swiss mathematician Paul Erdős, is "0=0". This may seem trivial, but it's a valid example of an inequality that holds true in all mathematical contexts. Erdős himself coined this phrase, and it has since been widely cited as the shortest equation in mathematics. The simplicity of this equation belies its profound implications, as it highlights the fundamental nature of mathematical equality.
