Hello Martina! I'm an English native who would love to learn Italian. Perhaps we could help each other out? 

Have a good evening.

I'm no teacher but English is my native language and I've been speaking it for 22 years. That being said how may I help you?

I am English native (From America). What might you need help with?

Also if I may add on a bit "isn't" is a combination of both "is" and "not", just like "aren't" is a combination of "are" and "not". There is no difference you see it's just merely shortening the two phrases into one.

It means collectively as a whole they have .27 cents. Apart they would have less but when they put their money together they have that much between them. Think of it as like a group of people and all of them have a few pennies but "between them" they have say a dollar. Does that make sense?

a shocking thing and my thinking

I must say my English words are very limited, and the grammar mistake may be very serious. I see you can read the article reluctantly and check or even remark it.
I am 20 years old this year, and I am Chinese in Zhejiang. Today I find this piece of software and use it.
It shocks me that so many foreigners who stay here are from all over the world .I also read some articles some people write in Chinese and revise them. I find many ridiculous mistakes they make which makes me know the errors are universally existed, but we should be good at asking for others.
I major in accounting and love it. If you want to know about Chinese and accounting, you can connect with me.
That's all. Thanks for reading.
