下記ソースは中学生向け無理数の説明図です。各かっこの上を各文字のアタマに そろえるにはどうしたらよいでしょうか。このような図がどこかにあったような記憶があるの ですが見つかりません。 %%%%%%%%%%%%%%%%%%%%%%% \documentclass{jsarticle} \begin{document} %%%%%%%%%%%%%%%%%%% \begin{eqnarray*} %%%%%%%%%%%%%%%%%%% \left. \begin{array}{crr} %%%%%%%%%%%%%%%%%%% \left. \begin{array}{crr} %%%%%%%%%%%%%%%%%%% \left. \begin{array}{lll} 自然数 N\\ 0\\ 負の自然数 \end{array} \right \} %%%%%%%%%%%%%%%%%%% 整数Z\\ 分数 \end{array} \right \} %%%%%%%%%%%%%%%%%%% 有理数Q\\ 無理数 \end{array} \right \} %%%%%%%%%%%%%%%%%%% 実数R(負の数を二乗すると必ず正(プラス)になる数の世界) %%%%%%%%%%%%%%%%%%% \end{eqnarray*} %%%%%%%%%%%%%%%%%%% \end{document}
