Propri\u00e9t\u00e9 de l\u2019addition :<\/strong>
L\u2019addition est commutative, on peut changer l\u2019ordre des termes sans changer la somme.<\/p>\n\n\n\n

Exemple :<\/strong> 2 + 3 = 3 + 2<\/p>\n\n\n\n

Conclusion :<\/strong>
On peut calculer des sommes en regroupant des termes astucieusement.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Propri\u00e9t\u00e9 de la multiplication :<\/strong>
La multiplication est commutative, on peut changer l\u2019ordre des facteurs sans changer le produit.<\/p>\n\n\n\n

Exemple :<\/strong> 2 x 3 = 3 x 2<\/p>\n\n\n\n

Conclusion :<\/strong>
On peut calculer un produit en commen\u00e7ant par la multiplication que l’on veut.<\/p>\n<\/div>\n<\/div>\n\n\n\n
