There was this popular girl in Facebook who had many followers. One day, she posted this post in her Facebook for fun and engagement:
It's lazy facts day!
Comment one lazy fact down below!
So the lazy facts started pouring in.
There were "The sky is not always blue", "Chocolates are sweet", "I had oatmeal for breakfast", etc, etc.
Among the lazy facts was a comment that only read two hearts.
This comment was posted by a mathematician. Nobody understood it. The mathematician was bewildered. "Pulleeze! Don't you know basic math???" he kept replying to the questioning comments on his comment.
What was going on?
Why did the mathematician expect everyone to understand his comment of only two hearts?
