On voit un panneau \u201cJe parie que tu as tort !\u201d, on fonce\u2026 et on tr\u00e9buche sur l\u2019ordre des op\u00e9rations. Pas de panique : avec la bonne routine, ces pi\u00e8ges viraux deviennent des formalit\u00e9s.<\/h2>\n

  1. Parenth\u00e8ses d\u2019abord.<\/li>\n
  2. Multiplications et divisions ensuite, de gauche \u00e0 droite.<\/li>\n
  3. Additions et soustractions enfin, toujours de gauche \u00e0 droite.

    Deux points essentiels :<\/p>\n

      \n
    • Multiplication et division ont la\u00a0m\u00eame priorit\u00e9<\/strong>\u00a0: on les r\u00e9sout dans l\u2019ordre o\u00f9 elles apparaissent.<\/li>\n
    • M\u00eame principe pour addition et soustraction.<\/li>\n<\/ul>\n

      Pourquoi tant d\u2019erreurs ?<\/h2>\n
        \n
      • Lecture pr\u00e9cipit\u00e9e de gauche \u00e0 droite, sans appliquer la priorit\u00e9 de la division.<\/li>\n
      • Ajout mental de parenth\u00e8ses qui n\u2019existent pas.<\/li>\n
      • Confusion entre \u201cla multiplication passe avant la division\u201d (en r\u00e9alit\u00e9, elles ont le m\u00eame rang).<\/li>\n<\/ul>\n

        Antis\u00e8ches express<\/h2>\n
          \n
        • Rep\u00e9rez d\u2019abord toutes les divisions\/multiplications et r\u00e9solvez-les dans l\u2019ordre d\u2019apparition.<\/li>\n
        • Ensuite seulement, g\u00e9rez les additions\/soustractions.<\/li>\n
        • Si une expression vous semble floue, ajoutez des parenth\u00e8ses pour visualiser correctement la hi\u00e9rarchie des calculs.<\/li>\n<\/ul>\n

          Le \u201cvrai\u201d pi\u00e8ge moderne<\/h2>\n

          Les expressions compactes comme\u00a08 \u00f7 2(2+2)\u00a0font souvent d\u00e9bat sur Internet car elles sont ambigu\u00ebs. La bonne pratique ? Toujours ajouter des parenth\u00e8ses pour expliciter votre intention. C\u2019est la cl\u00e9 pour faire partie du\u00a01 % qui ne se trompe jamais<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
