  • Scientists studied machine-learning models that perform multiplication tasks in experiments.
  • Many small models could not produce correct final answers consistently.
  • These models failed because they could not keep intermediate results.
  • Researchers used a new training method to change this behavior.
  • The new method helped models store and reuse running calculations.
  • After training, some models gave correct answers on tests.
  • The study shows training methods can change how models think.
  • This finding can help improve AI in real decisions.
