## Corrigé

1. **A) 44.** Ajouter 10 à un nombre à deux chiffres augmente le chiffre des dizaines de un, donc 34 + 10 = 44.

2. **Vrai.** La propriété associative dit que l'ordre d'addition ne change pas la somme, donc regrouper 20 + 30 en premier ou 30 + 5 en premier donne quand même le même total.

3. **17 autocollants.** Puisque 47 − 30 = 17, Maria a donné 17 autocollants.

4. **C) 70 et 30.** Seul 70 + 30 donne 100, puisque 40 + 50 = 90, 60 + 30 = 90, et 80 + 10 = 90.

5. **Exemple : 5 + 5 + 5 = 15 et 10 + 3 + 2 = 15.** Toute combinaison de deux ensembles de trois nombres totalisant 15 est correcte, puisqu'une somme peut être composée de plusieurs façons.

6. **87 centimètres.** En additionnant les deux longueurs, 62 + 25 = 87, on obtient la longueur totale des deux rubans.
