What happened at the 2024 World Cup
The Mental Calculation World Cup is organised by Ralf Laue and held in Germany. The 2024 edition ran on 14 September at the Heinz Nixdorf MuseumsForum in Paderborn, a museum of computing, and drew 35 competitors from 16 countries. The published results show Mishti Dharmesh Shah of India in second place in two of the four standard disciplines: addition, with 23 correct answers scoring 22 points, and multiplication, with 21 correct answers scoring 17 points.
The official results of the World Cup place her fifth overall for the combined competition. The World Mental Calculation summary of the same event lists her discipline placings without stating an overall standing, so the fifth place rests on the competition's own results tables at recordholders.org.
The competition, and who won it
The World Cup is built around four standard events: calendar calculation, addition, multiplication and square roots. In 2024 these were joined by five surprise tasks announced during the competition itself, making nine events in total. The surprise element is deliberate. It rewards competitors who can improvise a method under pressure rather than those who have drilled one narrow class of problem.
The 2024 title went to Aaryan Shukla of India, then 14, with 819.84 points; he had also won in 2022. That Shah finished in the top five of the same field, and second in two separate disciplines, places her among a small group of competitors capable of holding pace with the world's fastest calculators over a full day of events.
Addition and multiplication, in numbers
The two disciplines in which she placed second are the oldest and most unforgiving in the sport. Addition asks for repeated sums of long strings of digits against the clock; multiplication asks for products of large numbers carried entirely in the head. Scores are awarded on both accuracy and the number of problems completed, which is why 23 correct answers in addition converted to 22 points and 21 correct in multiplication to 17.
Those two second places came in a single day of competition. Nothing in the published results describes how she trains, how long she has competed or what method she uses, and no interview with her appears among the sources used for this page.
What is documented, and what is not
What can be stated with confidence is narrow and precise: her country, her two second places at the 2024 World Cup with the exact scores, and her fifth place overall in the official results. That is the whole of the documented record here.
Her age, date of birth, home city and school are not stated in any source used. Whether she competed at earlier editions of the World Cup, including the 2022 event, is not confirmed in the pages checked here. Nothing documents what she has done since September 2024, and no family or teacher is named.
Why a top-five finish matters
Mental calculation competitions are small by design. A field of 35 people from 16 countries is not a mass event; it is close to the entire active elite of the discipline in a given year. The people in that room have usually spent years on the same narrow families of problems, and the margins between them are measured in single-digit points.
Within that field, a competitor who takes second in two of the four standard events is not an outlier who got lucky on one task. India has produced several of the strongest recent competitors, including the 2024 champion, and Shah's placings put her inside that group rather than alongside it. What the record does not yet contain is the rest of her story.
