Talent is a special or more dominant potential or ability possessed by someone who can develop through an intensive training or education process. Strength Typology 30 (ST30) views talent as the role of individuals who have eight clusters, namely: Servicing, Thinking, Reasoning, Elementary, Networking, Generating Idea, Technical, and Headman. This research aims to describe how mathematical creative and critical thinking abilities of students who have dominant talent in cluster thinking, reasoning, and generating ideas. The instrument used in this research was a talent assessment (ST-30) through temubakat.com and a mathematical critical and creative thinking skill test on Numerical Method problems. In this research, one research subject was chosen who has dominant talent in the 3 clusters. The dominant talents of subject CLC in the cluster of thinking, reasoning, and generating ideas are Analyst, Strategic, Creator, and Synthesizer. The results showed that CLC subjects had good mathematical critical, and creative thinking skills. He can conduct all aspects of critical thinking skills (focus, reason, inference, situation, clarity, overview) and aspects of creative thinking ability (fluency, flexibility, originality) in solving Numerical Method problems.
