随分昔にFX-９９１を使っていたが、現在の物は、大変関数も増え、数式も表示されるので、間違えてもその部分に戻って修正できるのがうれしい。残念なのがメモリの操作が面倒な所。特にメモリクリアはキー操作して、出てきたメニューから選ばないといけない。ワンキーで出来る様に設計してほしかった。

J’ai acheté cette calculatrice Casio pour mes cours et je suis vraiment satisfaite. Elle est facile à utiliser, les touches sont réactives et l’écran est clair même après plusieurs heures d’utilisation. Elle gère parfaitement les fonctions scientifiques dont j’ai besoin pour les devoirs et les examens, et je trouve qu’elle est bien conçue pour les étudiants. Le manuel est aussi utile pour comprendre certaines fonctions avancées. Le rapport qualité-prix est excellent je la recommande vivement à tous ceux qui ont besoin d’une calculatrice performante et durable.
