How To Get Started

This math program is for anyone ages 3 to 103, wanting to improve their arithmetic skills, develop mental calculation or simply improve their brain functions.

Building amazing mental calculation capabilities with both speed and accuracy is what it's all about!

Just activate your 7-day free trial or purchase a monthly or annual subscription.

For Mental Calculations and Soroban programs you will also need a Japanese abacus called soroban. You can buy it on our website or anywhere else on the web. Although we recommend using a physical device, you can also use any of the abacus apps on a smart phone.

Purchase a one year subscription to SumoMath.com for someone you care about. From age 4 to 94, this gift will make a difference...

At the time of purchase, you will be able to send a personal note, which will be emailed to the recepient of the gift along with the details and instructions.

Our program is extensive and multi-dimensional. One can easily keep training on it for years. It was designed for older students to learn on their own, and for parents of younger kids to have all they need to assist.

Coaches add another layer to our program, to help you be most effective and efficient on your learning journey. Practitioners themselves, our expert coaches will spot and point out the little easily-missed details that will often make a huge difference in your training, keep an eye on your finger mechanics, guide you on the best ways to use our program and software, and just provide some extra motivation...

Coaching sessions are once a week for 20 minutes on Zoom. At the time of subscription creation, you will be able to request day and time that works best for you. If we are unable to match that time, we will offer some alternatives. Feel free to email us before subscribing to determine the schedule. You can subscribe just for a month to help you get started, or have a recurring weekly meeting for the student to look forward to, achieve goals and attend to difficulties.
