Math in chess?

I've always heard that chess involves math. If so, can someone explain where math is used?

There is no math. but being able to calculate variations 12 moves deep helpes

All math is problem solving, just like all chess is problem solving

Each piece has a numerical value which is counted to determine material advantage. This would be the simplest answer to your question.

Never heard about chess involving math. Sure evaluating exchanges involves some basic arithmetic to see if the material balance favours you, but that is over simplifying the values of pieces and positions.

The calculations in the context of chess have nothing to do with anything that gives the word meaning in mathematics.

Computer chess involves some math in the form of evaluations of positions and some algorithms. However, unless you want to program your own chess engine, chess and math have next to nothing to do with each other.

This is why children with very little formal education can become Grandmasters, because chess is a skill of its own that requires no other knowledge.

#2 calculating variations doesn't need math

I think, however, that the topic of corresponding squares may be related to graph theory.

#7 It might be related but do you think graph theory allows us some extra insight into the topic of related squares? If not then it's a moot point.

Math is about logical thinking. So there is a vague relation :)

#8 likeawizard, only a real expert of graph theory might answer your question.
However, it would be already great (IMO) to find, in this theory, a foundation (explanation) for the corresponding squares, which might otherwise appear to be a sort of trick.
