Bonjour, Je dois calculer la durée d’un événement entre le début et la fin. j’ai essayé de faire sur une ligne de temps, ça me donne 1h24 min au total. et j’ai essayé la méthode plus rapide en faisant directement une soustraction 14:51-13:27=1h23 ca donne pas la même réponse mais presque. Est ce que pour résoudre la durée d’évènement, je dois toujours dessiner une droite ou je peux juste faire rapidement une soustraction? merci😊
