How Japanese students multiply

How many lines u gonna draw for simple calculations like 99x18

real Japanese students ↓

I'm Japanese, but I don't know about this.

A little bit easy with Vedic maths Say you want to multiply 78x93 Step 1: Multiply the first digits of both the numbers (8x3 =24, keep the first digit 4 and carry 2) Step 2: Cross multiply the digits and add them and add the carried digit ( 7x3+8x9+2=95, keep first digit 5 and carry 9) Step 3: Multiply the third digits of both numbers and add any carried digit (7x9+9=72) Answer is 7254 Would be a bit complex for 3 digits x 3 digits

It actually works!!! 👌👌👌

日本ではこの方法は教えていない

In Japan, this calculation method is not used.

I'm from Japan and never see this multiply method. Who is the "Japanese student"? At least it"s not standard in Japan.

私は日本人ですがこのような方法を使ってる人は周りには居ませんね…
