Modern scheduling

01 仕組み How it works

Memory has a half-life. We schedule around it.

Left alone, a new word fades within days. FSRS, the algorithm behind modern Anki, models your personal forgetting curve and lifts each word back up at the last useful moment. Fewer reviews, better retention.

1.01365 = 37.8
0.99365 = 0.03

A little every day beats a lot once in a while. The difference between one percent better and one percent worse, over a year, is the whole game.

答え

こたえ

Save

An answer, reply, or solution to a question or problem.

Other Forms
1 Noun

Answer / Reply

答え(こたえ) means the content of an answer, not just the act of responding.

Use it for the information someone gives in response to a question. It comes from 答える(こたえる), meaning to answer.

Compare 返事(へんじ): 返事 is a reply or acknowledgment, like responding during roll call. 答え is the actual information that answers the question.
