IMO 2007 logo

The two perpendicular lines signify the co-ordinates of maths as well as the meridian and the parallel of latitude. The symbol of Hanoi capital (temple of literature, the first university founded in 1076), located at the intersection point of those two lines indicates the place where the 48th IMO will be held.

The two curved lines imply the interior powerful tension turning around the Hanoi symbol. On the one hand, it symbolizes the convergence, association, solidarity and friendship of youth at IMO, on the other hand it creates the image of the torch light, symbolizing the discovery of talents, the creativeness of youth, enhancing the Maths work to serve the noble objective of human being.
