億兆電卓

Read full description

『億兆電卓』は、ゼロを何度も押すことなく、国家レベルの大きなケタの数字を計算できる便利な計算機です。 また、3ケタ区切りのカンマがあるので、決算書を見慣れている人にも使いやすく、打ち間違いや、読み間違いを防ぐことができます。そして、計算式も残りますので「検算」にもとても便利です。 テレビのニュースでよく聞くような「何兆円」という大きな数字も日本国民『1.2億』人の数字でわり算することによって、個人の実感の持てる数字として認識できるようになります。 もちろん広告なしで無料です。なによりも、小さなお子様のファイナンス教育の一貫として、大きな数字を簡単に一瞬で扱えるツールとしてご利用いただければ開発側として幸いです。
