Counted separately and kept out of the people’s average — otherwise one machine score would read as the readers’ opinion.

Within learning apps, Speed Subtraction focuses on quick mental arithmetic rather than explaining a whole maths topic. Its Education category matches that purpose; by our assessment, the name makes the central task easy to understand. Repeated subtraction practice can build fluency, while a speed-focused format gives less room for learning why a method works. The useful measure here is whether answers become easier to recall without rushing past accuracy.
