this seems like as good a place as any to mention the etymology of the word mathematics. according to wikipedia,

The word mathematics comes from the Ancient Greek word máthēma (μάθημα), meaning ‘something learned, knowledge, mathematics’, and the derived expression mathēmatikḗ tékhnē (μαθηματικὴ τέχνη), meaning ‘mathematical science’.

so basically, math is the study of things that can be learned. 😎
