拼魔方的方法步骤 数学
网友回答
【答案】 为了记录下复原、转乱的过程或公式的步骤,会用Singmaster符号来书写（由David Singmaster发明）.书写方式如下： F、B、L、R、U、D分别代表前、后、左、右、上、下层. 若是顺时钟旋转,则直接写上符号；若是逆时钟旋转,则在符号后加上“'”或是“i”；若是旋转半圈,则在符号后加上“2”或是“²”. 若要更加详细纪录整个过程,还会使用以下符号： x、y、z分别代表将整个魔方做R、U、F,因为在速解魔方的时候,并不会总是将一个面朝向自己. f、b、l、r、u、d分别代表前、后、左、右、上、下两层,代表连中间层一起转. M、E、S代表旋转中间层,相当于l'L、d'D、f'F.在最少步骤还原的比赛中,规定： x、y、z不记步数. F、B、L、R、U、D旋转90°或180°都算做一步. M、E、S旋转90°或180°都算做两步.
