Unsure about other places, but how it works in my country: http://www.mondaq.com/india/x/784302/Copyright/Mathmatical+Equation+Per+Se+Cannot+Be+Copyrightable http://www.mondaq.com/india/x/784302/Copyright/Mathmatical+E... > In a legal sense also, you can copyright the content of a math book (such as diagrams, word problems, and illustrations) but the formula, problems, proofs, theorems themselves cannot be copyrighted. You cannot copyright a fact which is established and natural i.e., 1+1=2.
