Have you ever noticed it can be hard to learn to say and spell numbers in different languages because you never see them spelled out in writing? You might see "Uno Dos Tres, ..." in one chapter in your textbook, and then never again. So I created this app to to solve the problem (and just because I wanted to learn to count in other languages ;-). It's great for practice because it has a special "Odometer" style input that makes it easy to quickly count up and down by ones, tens, hundreds, etc. Of course it has a calculator-style input, too. And for practice recognizing numbers it has a fast-paced game: see the spelled number and tap in the digits as fast as you can. Here are some of the things Polynumial is useful for: • Quick translation of numbers into spelled-out words. • Learning to count in another language • Writing out a number on a check • Practicing number translation. It translates over 50 languages (see the list below). For most languages when you enter a number Polynumial shows the spelled-out version, like "cuarenta y dos" for 42 in Spanish. For many languages that aren't based on the latin alphabet it also supports the 'latinized' spellings, to help you remember how to pronounce them. So in Chinese the number 1,234 is spelled "一千二百三十四“, and the pronounceable version (in pinyin) is "yī qiān èr bǎi sān shí sì".
