Date of Record: 12/09/2022


Max Thomas-Wallis at 15 years of age manually calculated the 397 times tables x 16,000 = 6,352,000 on 68 pages of A4 paper.

Max is gifted in this area and when multiplying always chooses a random number that must be an odd number, as he prefers more of a challenge. Max adds 397 to the previous total, doing so in his head and faster than a calculator!
