On the three handwritten problems the author tested himself, Somo accurately found the erroneous line in each: one division-by-2 error, one missing negative sign when transposing terms, and one where the two sides of the equation were multiplied by different numbers; the author specifically notes that no real students have used it and that all test problems were written by himself.
