Romania have changed their shirt numbers to mathematical equations ahead of Sunday's friendly against Spain.
The unusual alteration to the squad's numbers is part of a national initiative aiming to improve Romanian children's interest in maths.
The school dropout rate in Romania, 18% in 2014, is currently one of the highest in the European Union.
The equations, which also feature on Romania's training kits, are set to be accompanied by a set of online manuals and an instructional video, which will be played before Sunday's match in Cluj.
Romania qualified for Euro 2016 in France after finishing second behind Northern Ireland in qualifying Group F.
