Mathematicus Interruptus

math•e•mat•i•cus in•ter•rupt•us |'mæθ•ǝ•'mæt•ɪ•kǝs ɪntɜ:ʳ•'rǝpt•ǝs|
1: an interruption of any mathematical process that can subsequently not be provided with a solution: The sudden ringing of a cell phone resulted in temporary mathematicus interruptus during the calculus exam.
2: the frustration that results from mathematicus interruptus, whether voluntary or not: For question number two, we were only required to set up the equation, not solve it, which caused me such intense mathematicus interruptus that concentrating on other questions became more difficult.
