Although mathematics certainly has developed shortcuts (e.g.: '3 + 2 = 5' for 'Three combined with two is five'), I don't think the intention was to remove English words. Rather, the intention was to remove ALL words, thus creating a 'language' that was portable throughout the known world. As a graduate student in mathematics a decade ago, I wrote quite a few proofs in English, and I'm quite certain that my professors would not have allowed mathematical abbreviations in my writing outside of the most basic (e.g.: '42' for 'forty-two'; 'n -1' for 'one less than "n"'). The reason for my confidence is because I attempted to use math notation in my writing back then, and I routinely failed to convince my professors that such was appropriate. From what I can tell, mathematical abbreviations are always to be used when working problems but only used when writing about problems when the alternative would be too inelegant. QED?
