摘 要: 提出一种简单、通用的速算算法,即普乘算法。该算法除了可以快速心算两个及两个以上的多位数相乘,还可以快速心算任意进制的多个多位数相乘,且该算法比常规两数相乘的竖式乘法方法更加简单高效。并通过大量的实例对该速算算法进行详细分析。
关 键 词: 数学基础;乘法速算;普乘算法;心算

Abstract: The paper presents a simple and common fast multiply calculate algorithm, which is named P-C algorithm. The algorithm can not only be fit to fast calculate the multiplication of two or more long numbers, but also fit to any others. The algorithm is simpler and more efficient than the normal vertical methods of two numbers’ multiplication, and is analyzed in detail through a lot of examples
Key words: foundations of mathematics; fast multiple calculation; P-C algorithm; mental arithmetic
