xn+1=xn+1⌊xn⌋x sub n plus 1 end-sub equals x sub n plus the fraction with numerator 1 and denominator the floor of x sub n end-floor end-fraction

Deep dives into roots and coefficients that require more than just Vieta’s formulas. Selected Problems of the Vietnamese Mathematica...

The Vietnamese Mathematical Olympiad (VMO) is legendary in the competitive math world for its grueling multi-day format and its penchant for "beautifully difficult" geometry and functional equations. xn+1=xn+1⌊xn⌋x sub n plus 1 end-sub equals x

Unlike the shorter, high-speed AMC or AIME exams, the VMO often feels like a marathon. Problems are designed to test deep structural understanding rather than just "tricks." Vietnam has historically been a powerhouse in the International Mathematical Olympiad (IMO), and the VMO is the sieve that catches their finest analytical minds.
