Mental Calculation Competitions in 2020 and 2021

For everyone curious about mental calculation competitions, there have recently been a lot of updates about the next events!

I was looking forward to attending some of these events, but unfortunately they’ve all been postponed until 2021 (except the MSO, which might not include mental calculation anyway).

This page has the latest updates about mental calculation events in 2020 and 2021, including estimated dates and an online competitions.

The page was written by me so feel free to reach out with any further questions. I know some readers of this forum are active in these competitions, so hopefully we’ll have the potential soon to compete!
