Présentation des concepts

Cette carte mentale traite des expressions numériques en abordant les opérations fondamentales (ordre des opérations, propriétés comme la commutativité, associativité et distributivité), les différents types de nombres (entiers, décimaux, fractions, notation scientifique, valeur absolue) et les techniques de simplification (factorisation, réduction des termes semblables, identités remarquables).

Les élèves appliqueront l'ordre des opérations (PEMDAS/Priorité des Opérations) pour résoudre des expressions numériques de complexité variable.
