Formal:
* 答案是 (dā'àn shì) - This is the most direct translation and is suitable for formal situations.
Informal:
* 答案就是 (dā'àn jiùshì) - This is a slightly more casual version that emphasizes the answer.
* 答案是… (dā'àn shì…) - You can simply use this and then follow it with the answer.
Example:
* Question: 1 + 1 等于多少? (1 + 1 děngyú duōshǎo?) - What is 1 + 1?
* Answer: 答案是 2。 (dā'àn shì 2.) - The answer is 2.
You can also say "your answer is" as:
* 你的答案是 (nǐ de dā'àn shì) - This is the literal translation of "your answer is".
* 你答对了 (nǐ dá duìle) - This means "you answered correctly."
Remember: The best way to say "and the answer is" in Chinese depends on the context and your audience.
