0.FFFF… = 1 (in hexadecimal) @MathVisualProofs

Uploaded January 2025 | Updated September 2026, 2 weeks ago

This is a short, animated visual proof showing the sum of the infinite geometric series with first term 15/16 and ratio 1/16, which in turn allows us to compute the sum of the series of powers of 1/16 and determine an interesting base 16 (hexadecimal) representation of 1.
