Super calculatrice
Une super calculatrice avec beaucoup de fonctions dont les approximations des intégrales et des dérivées qui sont assez rares sur des calculatrices non graphiques ainsi que toutes les fonctions usuelles. Je préfère certaines autres casio pour la répartition des touches, mais il suffit de beaucoup l'utiliser, rien d'impossible. Autre bon point : elle fonctionne au solaire et aux piles, donc beaucoup moins de risques de se trouver sans calculatrice à un moment important. La capot est parfait, la couleur change du sempiternel vert de casio. Pour les physiciens/chimistes il y a même les constantes physiques généralement utilisées, donc au lieu de devoir sortir son téléphone en cas d'oubli, elles sont à portée de main. En somme une calculatrice géniale, un peu dure à prendre en main suivant la calculatrice que vous avez eu avant, mais rien d'insurmontable, et une calculatrice super pour tous les âges.
