## About this program

The SUPERTMATIK Mental Math International Competition is a school-based contest organized by Eudactica in Portugal, built around the SUPERTMATIK mental calculation card game. Students practice and compete by solving arithmetic operations mentally and as quickly as possible, using the standardized SUPERTMATIK game format.

The competition is primarily aimed at primary and lower secondary students, but some editions include older grades depending on the school system; participation is coordinated through schools and teachers rather than individual sign‑ups. Benefits include improved speed and accuracy in arithmetic, better concentration, and increased confidence with numbers. Because results are submitted online and rankings are published internationally, students can measure their mental math skills against peers from many countries.
