- runarberg 5y agoThis table on Wikipedia says the inequality symbols were first used in 1631[1]. However guillemets (« ») date to the mid sixteenth century[2] and are still used as quotation marks in many languages. Although according to the page about brackets[3], chevrons were the earliest form of brackets, however I couldn’t find a year. 1: https://en.wikipedia.org/wiki/Table_of_mathematical_symbols_by_introduction_date https://en.wikipedia.org/wiki/Table_of_mathematical_symbols_... 2: https://en.wikipedia.org/wiki/Guillemet https://en.wikipedia.org/wiki/Guillemet 3: https://en.wikipedia.org/wiki/Bracket#History https://en.wikipedia.org/wiki/Bracket#History

- User23 5y agoRecorde is one of those intellectual heroes I only learned of a few years ago. It seems like no big deal now, but using a symbol instead of words to represent am equation was revolutionary.
