Before my college days I used to multiply orthodoxly by this way.
But as time passed, I learned new things. I remember, In a Hindi magazine named “Bhaskar Lakshya”, I read an article in which a lecturer (apology, I don’t remember his name) had suggested how to multiply in single line (row). Today I thought that I should share this method on MY DIGITAL NOTEBOOK too.
I know there are many, who already know this method, but I think maximum people wouldn’t have any idea about this method. I found multiplicating this way, very faster – easier and smarter. The ‘only’ requirements for using this method is quick summation. You should be good in calculation and addition. Smarter your calculations, faster you’re.
I’ll try to illustrate this method below. If you had any problems regarding language (poor off-course) and understandings, please feel free to put that into comments.
Let we try to multiply 498 with 753.
I don’t know if there is any algorithm behind it. The pattern of calculation is very obvious, making crosses and adding numbers.
You can use this method, multiplying larger numbers too. Try this one at your own. Steps are marked for convenience.
