Hi ,

One threw of black paint on the ground blanc for a room square of 2m× 2m ,  matter how. Prove that if there are two points of the same color, which the distance is exactly 1 meter.

I'm not sure I understand. Your first sentence makes no sense. Could you explain it a bit more carefully?

A logarithm is just a misspelled algorithm.

Hi Shiiro;

I am not following you here.

In mathematics, you don't understand things. You just get used to them.

Shiiro, is this like a modern artist throwing paint at the canvas?

### Re: Distance of two points !

Here's what I think is being asked:

A can of black paint is thrown on a white canvas, measuring 2x2 metres. The paint lies randomly.

Show that no matter how the paint lies, it's possible to pick two points that are exactly 1m apart and both the same colour.

Don't worry though - Sesame Street can help!

Why did the vector cross the road?
It wanted to be normal.
