30-Second Mental Math Test Guide

The 30-second mental math test is a quick speed drill for warmups and short practice breaks. It is useful when you want to check calculation rhythm without starting a long session.

A strong score is not just fast; it is fast with controlled accuracy. Use this test to wake up speed, then move to longer tests if you want endurance.
