Savoir répondre facilement à de nombreuses situations de la vie quotidienne, cela permet d'abord d'éviter de passer pour un idiot: - à la boucherie: on m'a rendu sur mon billet de 100, mais est-ce correct? (Je voudrais vérifier discrètement) - pendant les soldes: -30 % -40 % -50 %: quelle est la bonne affaire ? - au restaurant: on partage la note à 3 ? ça fait combien chacun ? - à une amie qui donne sa date de naissance: ça lui fait quel âge? Alors quel plaisir de découvrir que le calcul c'est simple, et même mentalement, et que l'on est finalement un génie qui s'ignore. Dans ce livre vous découvrirez une présentation originale, laissant une large part au visuel et qui rend simple tout ce que vous avez appris pendant votre scolarité - des techniques pratiques, sans formules mathématiques rébarbatives, utilisées par tous les grands calculateurs, - une application immédiate dans les principaux calculs de la vie courante. Et puis quel bonheur de pouvoir répondre à cette amie, sans lui parler de son âge: Tiens, c'était un vendredi !
