What if the “wrong” way to add fractions was secretly a key to understanding advanced mathematics? This exploration reveals how the “mediant”—adding numerators and denominators directly—offers an intuitive grasp of Simpson’s paradox. This seemingly simple error is then used to construct the Stern-Brocot tree, visualize number theory with Ford circles, and prove a fundamental theorem on rational approximation.
The ‘Wrong’ Way to Add Fractions is Actually Genius
What begins as a simple mathematical mistake unfolds into a surprising journey through advanced number theory, statistical paradoxes, and the hidden beauty of rational numbers.
