About Math Ninja

Math Ninja is striving to make all children succeed in a math, by making them a math warrior.

Our history

Math Ninja is founded in San Francisco, CA in 2017. Our Founder has been in the high-tech business in Silicon Valley and saw the current trend of employment. While the qualified engineers are mostly from overseas, we found a fact the American elementary school-aged children need to catch up on the level of math skills than their counterparts possess in other industrial and emerging countries, to be more competitive. To improve their basic math skills by utilizing the Soroban to teach calculation and mental calculation. The Japanese abacus, called, “Soroban”, was modified into the modern configuration. It has five-beads in each column, one-bead in the upper deck and four-bead in the lower deck. The Soroban/Abacus helps to perform mainly addition, subtraction, multiplication, and division.

Our vision

The soroban has been an excellent educational tool for children to visualize numbers. In addition, practicing soroban gives people an opportunity to develop their mental calculation ability. After mastering the soroban, the student will not need a calculator and become capable of calculating numbers by visualizing soroban beads. By cultivating the ability of mental calculating skills in pre-school and elementary students, they will have a better understanding of more complex problems in math by developing great concentration. As a result, they have a good school record not only on math but also on other subjects. As this proves, soroban is not just a calculation tool, but an excellent instructional tool itself.

Our mission

Math Ninja is striving to make all children succeed in a math, by making them a math warrior. So that no child needs to struggle with the math fatigue. We provide a gamification element of fun to mental calculation. We believe, If the child succeeds in math, they gain self-confidence to achieve higher in other subjects academically, and then become a contributing member of the society.

Math Ninja’s goals:

  • Foster a child’s confidence in the calculation.
  • Develop a mental calculation skill.
  • Enhance problem-solving capability.
  • Improve memory capacity.
  • Improve focus and mental endurance.
