Japanese Stick Multiplication

You re right i m talking about an array.

Japanese stick multiplication. The method is also known as indian multiplication and chinese stick multiplication but it is not known if it actually did originate from japan india china or elsewhere. A viral tiktok video shows an old unique way to multiply using sticks. It may come from china japan or somewhere else. Whatever the roots.

In order to understand how japanese multiplication works we must start back at the good old reliable method of organizing equal groups in rows and columns. People have called it chinese stick multiplication or how the japanese multiply without source. The earliest reference i can find is a youtube video dated nov 22 2006. When we say 3 times 2 that is the same as saying 3 groups of 2 and we can show these three groups as 3 rows and 2 columns or 3 columns and two rows.

Validation when it comes to multiplying two numbers of multiple digits most people use the traditional vertical method that is taught in most elementary schools. I could not verify this method is actually taught in china or japan.
