info How ZestMath catches carrying errors

The most common addition mistake at every level is the carry error: a student adds the units column correctly but forgets to carry the ten, or carries when they shouldn't. ZestMath detects carry errors by checking whether a wrong answer is exactly 10 or 20 less than the correct answer — a reliable signature of a missed carry. When this pattern appears on 3 or more questions, the results page flags it explicitly.
