Common mistakes

1. Using the infinitive instead of a conjugated form

✗ Wrong: “Je calculer le prix total.”

✓ Right: “Je calcule le prix total.”

The infinitive calculer never takes a subject. After je you need the conjugated present form calcule.

2. Confusing calculer with compter

✗ Wrong: “Je calcule les pièces sur la table.” (meant as “compter”)

✓ Right: “Je calcule le prix total.”

calculer means “to calculate”; compter means “to count”. Keep the two verbs apart by their meaning, not by their sound.

3. Using the wrong auxiliary for the passé composé

✗ Wrong: “Je suis calculé le prix total.”

✓ Right: “J'ai calculé le prix total.”

With calculer the passé composé is formed with avoir, not être: ai calculé.

4. Using the indicative after a subjunctive trigger

✗ Wrong: “Il faut que je calcule le prix total.”

✓ Right: “Il faut que je calcule le prix total.”

After il faut que French needs the subjunctive, so use calcule here, not the indicative calcule.

5. Using the present for a finished past event

✗ Wrong: “Je calcule le prix total hier.”

✓ Right: “J'ai calculé le prix total hier.”

Yesterday’s finished event needs the passé composé (ai calculé), not the present.
