A Simpler Elementary Proof That "e" Is Irrational
F. M. S. Lima1
International Journal of Mathematical Education in Science and Technology, v56 n3 p545-547 2025
In this short note I present an elementary proof of irrationality for the number "e," the base of the natural logarithm. It is simpler than other known proofs as it does not use comparisons with geometric series, nor Beukers' integrals, and it does not assume that "e" is a rational number from the beginning.
