解答をする

This is a standard 'suru-verb' combination. You take the noun 解答 (answer/solution) and pair it with the verb する (to do). In a sentence, you usually use the particle を to connect them. For example, 解答をする (to do an answer). If you want to be polite, you say 解答をします. If you already finished, you say 解答をしました. It’s a very reliable pattern that is easy to conjugate once you know the basics of する!

This phrase shines in academic settings. Use it for math problems, science tests, or history exams. It’s also perfect for formal surveys or official questionnaires. If you are at a job interview and they give you a written logic test, this is the word you’ll hear. You might also use it when discussing the 'official' solution to a riddle or a logic puzzle. It feels professional and serious.

Don't use this for casual conversation. If your friend asks 'What do you want for dinner?', don't say 解答をする. That would sound like you're treating dinner like a calculus exam! Just use the simpler word 答える (to answer). Also, don't use it for 'solving' a life problem or a conflict between friends. For those 'solutions,' Japanese uses 解決する. 解答 is specifically for 'answers' to 'questions.'

Japan is famous for its 'Examination Hell' culture. Students spend years preparing for entrance exams. Because of this, words related to testing are deeply ingrained. 解答 isn't just a word; it's a symbol of hard work. There is a lot of pressure to provide the 'correct' 解答. You'll even see 'Answer Keys' sold as best-selling books in Japanese bookstores. It’s a high-stakes word!

You will often see 解答用紙 (answer sheet) or 模範解答 (model answer). If you are checking your work, you are looking at the 解答例 (example answer). These variations show just how much the Japanese language categorizes the act of answering. It’s all about being organized and correct.
