If this method "Mikado" you like, you will find, however laborious to calculate a product type: 867 * 948.
Another method is to perform a series of additions as follows:
With a little practice, it is easy to find the result of 2522144 * 2610117:
Unexpectedly, found with some additions the product of two numbers. It is therefore possible to perform multiplication without knowing the multiplication tables.
You know now that there are different ways to calculate a product and that the school has only one facet of it. If you are a teacher or just curious I invite you to react, of course:)
PS: Obviously it is important to know their multiplication tables and the article is not intended to encourage students to ignore the above. Sometimes we hesitate even for adults, today I still review whether if table 13, 17 and 19 in soon ... tough
