This School was set up with the specific aim of training boys in navigation techniques so that they could serve the King at sea. Moore became a governor of the school and together with Perkins, a master at the school, he wrote a major mathematical work intended for use at the Royal Mathematical School. Moore died however before the work could be published.
Moore, kasama ang mga bantog na talaarawan writer Samuel Pepys, itinatag ang Royal matematiko School sa loob ni Kristo's Hospital. School na ito ay na-set up sa mga tiyak na layunin ng pagsasanay Boys sa navigation pamamaraan upang ang mga ito ay maaaring magsilbi ang hari sa dagat. Moore na naging gobernador ng paaralan at kasama ng mga Perkins, ng isang master at ng paaralan, siya wrote isang malaking matematiko trabaho na para sa paggamit sa Royal matematiko School. Moore namatay subalit bago ang trabaho ay maaaring nai-publish.
