Answer 1

In mathematics, the four color theorem, or the four color map theorem, states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color.

Answer 2

Answer:

The four color theorem is particularly notable for being the first major theorem proved by a computer.

Interestingly, despite the problem being motivated by mapmaking, the theorem is not especially important to the field as most maps were historically drawn with more than four colors (despite only four being necessary). In addition, most maps occurring in practice only require three colors.
