Question 1 sur 10 10:00

[{"id":40926,"question":"Quel est le résultat de l'opération suivante : 3 + 5 × 2 ?","option_a":"13","option_b":"16","option_c":"11","option_d":"26","option_e":"","option_f":"","bonne_reponse":"A","explication":"La multiplication est prioritaire sur l'addition. Donc 5 × 2 = 10, puis 3 + 10 = 13.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":40927,"question":"L'équation 2x + 3 = 7 a pour solution x = 2.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"B","explication":"Si x = 2, alors 2×2 + 3 = 7, ce qui est correct. La solution est donc x = 2. Réponse : Vrai.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":40928,"question":"Résoudre l'équation 4x - 5 = 11.","option_a":"x = 4","option_b":"x = 3","option_c":"x = 5","option_d":"x = 2","option_e":"","option_f":"","bonne_reponse":"A","explication":"4x - 5 = 11 → 4x = 16 → x = 4.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0},{"id":40929,"question":"Le résultat de 15 ÷ 3 × 2 est égal à 10.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"A","explication":"15 ÷ 3 = 5, puis 5 × 2 = 10.
