“The competition was on July 20th at 10:00 a.m.. We were all very happy, I noticed Sergio  was a little bit nervous one month ago, but right before the competition he was very relaxed, had no anguish or nervousness, was very calm and confident,” said his mom.

Through the program ALOHA Mental Calculation, Sergio Antonio obtained the first place in the children’s category of mental calculation at state level in Querétaro, Mexico. Later he participated in the national contest where he won the “Copa de Excelencia” (Excellency cup).

The method for performing mathematical operations consists of visualizing the Japanese abacus.
