未被选中。
即尝试选择以下段落并通过单击按钮突出显示它。
"The remainder is r when p is divided by k" means p = kq + r; the integer q is called the quotient. For instance, “The remainder is 1 when 7 is divided by 3” means 7 = 3·2 + 1. Dividing both sides of p = kq + r by k gives the following alternative form p/k = q + r/k.
除上述段落外的所有其他作品。
