How about this. Heya ni isu ga mitsu arimasu. Is that correct?

Is there a "more correct" order? In languages with less strict word order there tends to be word orders that sound more natural or imply emphasis on the subject or object.

Something to keep in mind!

haha! i lol'd

Yes, that is a grammatically correct sentence. And (@Tanja) it is indeed possible to connect 2 particles to 1 noun, like へやには.

Partially. へやにいすがあります ought to be a valid alternative, considering the word order in the previous exercises. But you cannot put two particles on the same noun, like へやには.

I'm really disliking how they give you the kanji in the notes and then forbid you to use them in the answers themselves, and there's not even the option to report "My answer should be accepted" most of the time.

In this case 三 is pronounced み or mi. Kanji can have many pronunciations depending on what follows the kanji.

When it's with the "tsu", it's read as "mittsu"

Counters are connected to the counted thing by:

• directly placing them next to each other: 三ついす｛があります｝
• linking them with a possessive particle 'no': 三つのいす｛があります｝
• following the topic/subject marker 'wa/ga': いすが三つ｛あります｝

So "In two rooms there are three chairs" would -for example- be: 二つのへやにいすが三つあります。

Most useful question I've read.

I didnt hear it either.. i was so confused but typed in what i heard (without ga) even though i knew it should have been there.

I can hear it but I think what is probably happening for the both of you is that が and あります are blending into each other, that, the speed of the speech and the unfamiliar language are making it hard for you both to hear the が.

No. Since we used が to establish that いす was the subject of our sentence, the counting adjective applies to it naturally.

It's because it is pronounced 'nga' - so it is pronounced, but probably different from what you expected!

This is my issue. It seems the rules with counters are more fast and loose in terms of placement...

Numbers/counters should either go between the verb and the last particle or modify the noun with the help of の.

The が is there, however it is elided with the start of あります, so perhaps that is the reason it is hard for you to hear?

The counter attaches to the number itself, wherever it is :)

These are correct except that 三つ cannot directly modify いす. It needs の in between to help the counter modify the noun.

Short version: が places clear emphasis on the subject. は is a more general topic marker.

Long version:

が is always used after question words, e.g. だれが来ましたか ("Who came?") as well as in the responses to such questions (松岡さんが来ました -> "mr/ms Matsuoka came"). If you write 松岡さんは来ました it's understood that Matsuoka was already expected to come, and this information could also have been left out (i.e. just 来ました would have sufficed).

There are also certain verbs that nearly always use が, such as いる・ある (to be), いる (to need), わかる (to understand/know) and できる (to be able to/to succeed). In these cases, the 'psychological' subject can be marked with は, while the grammatical subject takes が. E.g. （わたしは）ぺんがいります: "I need a pen". This is demonstrates why applying the grammatical rules of one language to a different one doesn't work; in English, "I" would be the subject and "pen" the object, but in Japanese the pen is the subject (it is being needed), while "I" is merely some extra info that might as well be left out.

Besides general phrases, は is used in sentences with (an implied) contrast between things, where the subject may not have an explicit emphasis, but can nevertheless not be left out from the sentence. E.g. フランスの子供はよくブドウ酒をのみます: "French children often drink wine" (in contrast to children from other countries).

Ha (wa) is usually used wheb establishing a new topic that someone is talking about. Ga would be used for referring back to the topic, or at least, thats how I view it. Image ga being used as "as for x" and ha (wa) being used as "this is x and this statement is about x"

は is used for animate things like animals while が indicates inanimate objects like a desk or a chair.

It's also used to mark locations.

The second of your examples would be correct if 三つ had の helping it modify the noun - I have noticed however that Duo regularly misses this の out at times. Also it is あります - Arimasu, not HArimasu - harimasu would be はります.

笑い

That would be more "there are 3 chairs AT the room"

Duolingo no califica puntuación.

Don't know why - I often type in the numeral and it's always accepted.

あります means to exist or 'is' or to have but is only used for inanimate objects. ～ます is a verb ending and would never be used on its own. では　ありません is the negative present active form of です.

Yes.

I was going to say that you might be finding it difficult to hear the が because it is followed directly by the あ of あります but when I listen to it even at the regular speed they seem quite clear and distinct to me. But I am used to it. That might be your problem though - the elision of sounds due to the speed of natural speech. Also I don't think you really want the speaker to slow down what they are saying, I think what you really want them to do is to enunciate each word clearly and distinctly from each other. While this is understandable for beginners, it won't do you any favours if your goal is eventually be able to understand and communicate fluently and fluidly in Japanese. If you don't get used to natural speech - both speed and elision or slurring together of sounds then you're gonna really struggle. Better to get accustomed to it sooner rather than later. Believe me - this is nothing compared to talking with children or elderly people - in addition to natural speed and elision they also often mumble, speak in low form and their voice pitch (high or low) can also make it very difficult to understand what they are saying!

Unfortunately it's impossible to tell when duo does and doesn't accept kanji on even given day. In fact it would be entirely accurate to say that Duo is consistently inconsistent in regards to accepting or not accepting kanji.

If you press enter after you type each word or character then it won't erase or change the characters/kanji that you've already typed. And as for which kanji duo accepts or when, that's anyone's guess. I would say if in doubt type it in kana. As for numbers, I would say that since duo introduces the kanji for numbers from the start with kana, that you should be safe always using the kanji for numbers.

Chair is in the sentence. Isu

I'm inclined to agree with SkylerHill1. The sentence specified chairs; otherwise it would have just stated something to the effect of 三つがあります。

Besides, sentences do not always come in the same order. The topic of your last sentence could have been something entirely different.
