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.
\nLa r\u00e8gle \u00e0 m\u00e9moriser (sans acronymes compliqu\u00e9s)<\/p>\n
Parenth\u00e8ses d\u2019abord.
\nMultiplications et divisions ensuite, de gauche \u00e0 droite.
\nAdditions et soustractions enfin, toujours de gauche \u00e0 droite.<\/p>\n
Deux points essentiels :<\/p>\n
Multiplication et division ont la m\u00eame priorit\u00e9 : on les r\u00e9sout dans l\u2019ordre o\u00f9 elles apparaissent.
\nM\u00eame principe pour addition et soustraction.
