意思不同，詞性不同，讀音不同。numerical是形容詞，意思是：數(shù)的，有關(guān)數(shù)的，用數(shù)字表示的，讀音是[nju??mer?kl]。numeral是名詞，意思是數(shù)字；數(shù)碼，讀音是[?nju?m?r?l]。

Your job is to group them by letter and put them in numerical order.

你的工作是把他們按字母順序分組，然后按數(shù)字順序排序。

Their numerical system, derived from the Babylonians, was based on multiples of the number six.

他們的數(shù)制源自古巴比倫人，以數(shù)字6的倍數(shù)為基數(shù)。

For the numerical solution of these problems large electronic computers must be used.

為了得到這些問題的數(shù)字解，必須使用大型電子計(jì)算機(jī)。
