👉 Banned math refers to mathematical concepts and methods that have been suppressed, censored, or deemed inappropriate by certain institutions, governments, or ideologies. These often include topics like non-Euclidean geometry, which challenges the traditional parallel postulate and has been banned in some educational systems due to its philosophical implications; fractals, which some have criticized for their perceived connection to chaos theory and the unpredictability of nature; and certain forms of topology that explore spaces with unusual properties, such as the Banach-Tarski paradox, which defies intuitive notions of volume and space. Other examples include the use of non-standard analysis, which introduced infinitesimals and has been banned in some curricula due to its departure from standard calculus, and the study of negative numbers and complex numbers, which were historically discouraged but are now fundamental to mathematics. These bans often stem from ideological, religious, or pedagogical concerns rather than mathematical inaccuracies.
