Rumors of this new mathematics competition reached Denmark, and in 1989 a single Danish student, who was very eager to participate, was allowed to write the exam in a school in Sweden. In 1990 more Danish students participated, so Matti Lehtinen could write in his report: "For the first time the NMO may now be called a common Nordic competition since all five Nordic countries participated with at least half a dozen pupils." (Translated from Swedish; the abbreviation NMO is elucidated in the section Name below.) Denmark was invited to host the NMC in 1991, the year Denmark entered the IMO, but since the Danish organisers were inexperienced, the Swedish organisers agreed to host the NMC for a second time. Denmark would then host the NMC in 1992 and again in 1996. In the future, the hosting order would be the present one: Sweden, Norway, Iceland, Finland, Denmark.
