Method of successive substitution formula to obtain the solution. Method of successive substitution In modular arithmetic, the method of successive substitution is a method of solving problems of simultaneous congruences by using the definition of the congruence equation. It is commonly applied in cases where the conditions of the Chinese remainder theorem are not satisfied. There is also an unrelated numerical-analysis method of successive substitution, a randomized algorithm used for root finding, an application of fixed-point iteration. The method of successive substitution is also known as back substitution. Consider the simple set of simultaneous congruences Now, for "x" ≡ 3 (mod 4) to be
Chess Olympiad the Olympiad. The tests were first introduced in 2002 under significant controversy, with the widespread belief that it was impossible to dope in chess. Research carried out by the Dutch chess federation failed to find a single performance-enhancing substance for chess. According to Dr Helmut Pfleger, who has been conducting experiments in the field for around twenty years, "Both mentally stimulating and mentally calming medication have too many negative side effects". Players such as Artur Yusupov, Jan Timman and Robert Hübner either refused to play for their national team or to participate in events such as the Chess Olympiad where
