Ces petits casse-t\u00eates math\u00e9matiques astucieux font fureur sur Internet ces derniers temps, et franchement, on comprend pourquoi.<\/p>\n
Ils paraissent simples au premier abord\u2026 jusqu\u2019\u00e0 ce que l\u2019ordre des op\u00e9rations nous surprenne tous\u00a0!\u00a0\ud83d\ude0f<\/p>\n
Repensez \u00e0 vos cours de maths au coll\u00e8ge et voyez si vous arrivez encore \u00e0 r\u00e9soudre ce d\u00e9fi !<\/p>\n
Le casse-t\u00eate<\/p>\n
Quelle est la bonne r\u00e9ponse \u00e0 cette expression\u00a0?<\/p>\n
50 + 50 \u2212 25 \u00d7 0 + 2 + 2 + 2 50 + 50 \u2212 25 \u00d7 0 + 2 + 2 + 2<\/p>\n
Prenez votre temps avant de faire d\u00e9filer la page.<\/p>\n
La plupart des gens sont press\u00e9s et se trompent\u00a0!<\/p>\n
La bonne r\u00e9ponse : 106<\/p>\n
Voici comment r\u00e9soudre ce probl\u00e8me \u00e9tape par \u00e9tape\u00a0:<\/p>\n
\u00c9tape 1\u00a0: La multiplication pr\u00e9c\u00e8de l\u2019addition<\/p>\n
25 \u00d7 0 = 0<\/p>\n
L\u2019\u00e9quation devient donc\u00a0: 50 + 50 \u2212 0 + 2 + 2 + 2<\/p>\n
\u00c9tape 2\u00a0: R\u00e9soudre de gauche \u00e0 droite<\/p>\n
50 + 50 = 100<\/p>\n
100 \u2212 0 = 100<\/p>\n
100 + 2 + 2 + 2 = 106<\/p>\n
\ud83c\udfaf\u00a0R\u00e9ponse finale\u00a0: 106<\/p>\n
L\u2019astuce consiste \u00e0 se souvenir de l\u2019ordre des op\u00e9rations\u00a0:<\/p>\n
la multiplication et la division pr\u00e9c\u00e8dent toujours l\u2019addition et la soustraction.<\/p>\n
Alors\u2026 avez-vous trouv\u00e9 la bonne r\u00e9ponse du premier coup\u00a0?\u00a0\ud83d\udc40<\/p>\n
