Column subtraction with borrowing is where most of the errors live. The classic one is not arithmetic but direction: seeing 3 − 7 in the ones column, finding it impossible, and quietly answering 4. Every answer can be checked by adding it back to the number subtracted, and building that habit matters more than any single fact.
