Arabic numerals get upcast to dates if > 50 #141
Description
Alexa actually doesn't understand arabic numerals. Instead it wants the written words, e.g., "eighty eight" rather than "88." This has important implications for the Alexa Voice Calculator because it can appear as though the results are incorrect. We should include a note in the Voice Calculator tutorial that people should write out the numbers in English rather than writing them as numeric values.
