Input: Read this: Until recently, in most critical writing the post-punk era was "often dismissed as an awkward period in which punk's gleeful ructions petered out into the vacuity of the Eighties". Contemporary scholars have argued to the contrary, asserting that the period produced significant innovations and music on its own. Simon Reynolds described the period as "a fair match for the sixties in terms of the sheer amount of great music created, the spirit of adventure and idealism that infused it, and the way that the music seemed inextricably connected to the political and social turbulence of its era". Nicholas Lezard wrote that the music of the period "was avant-garde, open to any musical possibilities that suggested themselves, united only in the sense that it was very often cerebral, concocted by brainy young men and women interested as much in disturbing the audience, or making them think, as in making a pop song".

Input: Read this: Comparison of a back-translation with the original text is sometimes used as a check on the accuracy of the original translation, much as the accuracy of a mathematical operation is sometimes checked by reversing the operation. But the results of such reverse-translation operations, while useful as approximate checks, are not always precisely reliable. Back-translation must in general be less accurate than back-calculation because linguistic symbols (words) are often ambiguous, whereas mathematical symbols are intentionally unequivocal.
Question: How are mathematical operations ignored?

Output:
unanswerable
