Mathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific, fixed meanings in particular areas of mathematics.
A special series of numeral adjectives was used for counting these, namely Å«nÄ«, bÄ«nÄ«, trÄ«nÄ«, quadrÄ«nÄ«, quÄ«nÄ«, sÄnÄ«, and so on. Thus Roman authors would write: Å«nae litterae 'one letter', trÄ«nae litterae 'three letters', quÄ«na castra 'five camps', etc.
