ラフル・ロビン

Rahul Robin is an Indian mental calculator from the state of Jharkhand. Displaying a high quantitative and visualization ability from early childhood, Robin was highly accelerated in academic mathematics and used to be known for memorizing batches of phone numbers. When the pandemic hit, Robin began practicing mental calculation more formally, with a focus on oral calculations and multiplications, while also excelling at various online blitz mental arithmetic games.

Robin competed in Season 1 of Calculation League --- without significant prior experience in global calculation competitions --- and immediately demonstrated excellent visualization ability. Throughout the course of Season 1, he began developing his approach to more complex calculation questions, quickly improving along the way, and ultimately making the semi-finals and taking 4th place, a rank he retained in Seasons 2 and 3 after securing a variety of wins against highly experienced and accomplished mental calculators.

Robin prefers to do varied non-standard questions with mixed operations. He believes students of mental calculation should focus on practicing both oral and written questions and should emphasize versatility and improving skills in their weaker areas rather than repeated practice of specific tasks.

Robin holds a degree in civil engineering from NIT Jamshedpur.

暗算以外では、マルクはバレンシア工科大学で博士号を取得した数学者であり、彼の研究は確率微分方程式と分数階微分方程式に焦点を当てています。28歳で、彼は34歳以下の数学者による研究を対象としたスペイン応用数学会賞を受賞した最年少の数学者となりました。マルクは暗算と数学の関連性を分析することを楽しんでおり、特に高度な数学が、一見単純な算術問題を解くアプローチに情報を提供する際にその喜びを感じています。

マルクはまた、運動、特にヨーロッパサッカー、文献学、そしてそろばんの達人の研究も楽しんでいます。
