Summary[edit]

Description

It's 3rd month of 14th, it's pi day! Here is something interesting to know and easy to understand from math. The answers of last 2 multiplications are framed out, but I think you can easily guess the answers.

今日は3月14日でπの日なので、サクっとわかって、知って面白い数学の話をひとつ。 下の最後の2つの掛け算の答えが隠れていますが、規則性を見つければ簡単に答えがわかってしまいます。
