课程名称：人人都能掌握的心算乘法 课程概述：欢迎来到奥托·弗兰科的《心算乘法论》，他是一位计算机工程师和数学爱好者，创造了一个记忆99乘99乘法表的方法。课程强调在100为基数的情况下，心算的高效性，即将2位数作为1位数看待。这需要记忆大量的2位数乘法事实，例如89×72=6408。尽管记住3321个乘法事实看起来令人生畏，但通过有效的方法可以轻松应对。 课程的主要概念在于99乘99乘法表中各个乘法事实之间存在的紧密联系。例如，85×83=7055可以通过代数捷径2.1直接从84×84=7056推导出来。此外，基于84×84=7056，我们还可以推导出其他相关的乘法事实。课程中有许多这样的例子，所使用的技术大量依赖代数。因此，建议学员具备扎实的初等代数知识，以便充分理解课程内容。 如果您是数学家、数学爱好者或需要核实学生计算的数学教师，这门课程将非常适合您。课程内容由工程师奥托·弗兰科开发，而视频中的讲解则由一位优秀的英语教师进行。感谢您的收听，让我们开始吧！
Welcome to The Treatise on Mental Multiplication by O. Franco, Computer Engineer and Math lover who created a method to memorize the entire multiplication table up to 99x99.Mental math calculations can be performed more efficiently in base 100, that is, a 2-digit number is seen as a 1-digit entity. This requires memorizing a large number of multiplication facts of 2-digit numbers, such as 89×72=6408.Memorizing 3321 multiplication facts can seem daunting and intimidating, but it can be approached efficiently. The main concept in the memorizing process of the multiplication table up to 99x99 is the strong relationship existing amongst all the multiplications facts themselves within the table. For example, the multiplication fact 85×83=7055 can be directly derived from 84×84=7056 by applying the algebraic shortcut 2.1 (part of the course content). From the multiplication fact 84×84=7056 we can also derive 86×82=7052, 87×81=7047, and so on. 84×84=7056 in turn can be easily calculated from 84×6=504 by applying the algebraic shortcut 1.0. Furthermore, a large set of multiplication facts can be derived from 84×6=504 directly. Just like these there are many examples in the multiplication table. The techniques outlined in this course are based extensively on Algebra. Because of this, it is highly recommended to have a solid knowledge of Elementary Algebra in order to fully understand the content of the course.If you're a Mathematician, a Math lover or a Math teacher who needs to verify student calculations, this may be a very good course for you.The content of this course was developed by Eng. Otto Franco, and the narrator in the videos is an excellent English teacher.Well, thank you very much for listening and let's get started!
