Good night again.

As to the multiplication table in America,they needn't to learn by heart to 12の段, for they don't adopt the duodecimal system. It says in the book of ｢これを英語で言えますか？｣😁

Mathematics includes algebra,geometry,factorization(因数分解) and differental calculus(微分)、integral calculus(積分),so I can't undesstand mathmatics at all.😂

I tried express difference calculus and integral calculus,but I gave up it,for I failed the division of fraction.When calculating it,we need to turn the denominator(分母)and mumerator.😔

I can understand a simple one,for example one divide half, I can understand it easily why it is,but when being the denominator and numerator are large, I don't know why it is,though I can calculate it,for I only have to turn upside thd numbers.😚

See you later. Thd winter seems to continue,so let's take care of ourselvns each other.Have a wonderful night😁
