Are u asking me for the translation??

Big problem. :) Here is what you wrote:

Person A: Is Sue's area of specialty economics?
Person B: No, it isn't Japanese. It's computer.

See the issue above? You could say:

Person A:　スーさんのせんもんはけいざいですか。
Person B:　いいえ、けいざいじゃありません。コンピューター� ��す。
＿＿＿

I actually personally never say ～～じゃありません and neither do many other Japanese-speakers but if that's what you learn, let's not discuss it.

I use ～～ではありません. I couldn't quite see how someone could stand the imbalance between the highly casual じゃ and the not so casual ありません.

The first line does not make much sense. Context may help.

"One can convey Love just
by saying アイ or ハッ

It works like that
It works like that
It does work like that"

Again, there's a few questions I'd like to ask today.

1. This is just my guess based on the context, but does 差し引きゼロ mean both bad things and good things happened and they are equal?

2. What does ずずいっと mean? I can't find it in my dictionary.

3. ちょっとくらい缶ジュースを持つの手伝ってくれ
I'm not sure if I really understand the particle の correctly here, so I'll attempt to translate the sentence. Please correct me again if I make any mistake.

1. In this context, yes.

2. It means "without hesitation". It is the more colloquial form of ずいと.

3. It is the verb-nominalizing particle, which is why you can add the を to it.

Your translation is good.

Err, so can you tell me what it means in general?

Losses and gains canceling each other out.
Coming out even.

Thanks for the help so instead of ja armasen I can use ではありません. And I have a question about grammer the ね or よ. Ne is used for agreement?? And yo is used in a sentences like let me assure you tonkatsu is not fish. Is that how u would use them in a sentences ??

Thanks a lot. :) I was thinking of a short way to interpret it, but I couldn't.
