About Me
I am Jinansh Dedhia, a young prodigy who has taken the world of mathematics by storm. Recognized as the world’s youngest human calculator, I have an extraordinary ability to solve complex calculations with astonishing speed and accuracy. My passion for numbers and mental math has allowed me to break conventional boundaries and set new benchmarks in rapid arithmetic.
From an early age, I discovered my innate talent for numbers and was fascinated by the world of mathematics. Performing intricate calculations in mere seconds—without a calculator or pen and paper—has become second nature to me.
