Please log this mistake into my daughter's mistake notebook:
Problem: Calculate 3/4 ÷ 2/5.
Her wrong answer: She flipped the dividend instead of the divisor and wrote 4/3 * 2/5 = 8/15.
Correct answer: Keep-Change-Flip gives 3/4 * 5/2 = 15/8 (or 1 7/8).
Please record this card with tag fractions, cause inverted-wrong-fraction, and remind us to review it.
Answer
我先看一下 append_card 脚本的入参格式再调它。
记下了：tag `fractions`, cause `inverted-wrong-fraction`, new card id `3564a793d3f60e10`.
But I want to flag two things honestly before we move on.
**The same cause is already in your notebook three times.**
The skill this notebook follows says "same cause → one card" (otherwise 40 misses become 40 cards and the review becomes busy work). ight now your notebook already has, on this exact "flipped the wrong fraction" trap:
| id | prompt | cause |
|---|---|---|
| `b0614efd54ac729a` | `(3/4) ÷ (2/5) = ?` (literally the same problem) | `inverted-dividend-not-divisor` |
| `56d4861af486ddfa` | `2/3 ÷ 4/5 … 3/4 ÷ 2/3 …` (the exact "8/15" pattern) | `forgot to invert the divisor` |
| `c8df5940ce80f309` | `3/4 ÷ 2/5` (representative of 5 same-cause misses on the quiz) | — |
The card I just wrote is a fourth entry on the same cause. Today, all three of those are due for review. Adding a fourth means the same trap gets tested four separate days instead of once.
Two ways forward — your call:
- **Keep all four.** Each gets its own review slot. Same trap, four times.
- **Drop the new one** (`3564a793d3f60e10`). The existing `b0614efd54ac729a` already is this exact problem; review that one. (I can leave it in place if you'd rather see it once and then merge — just tell me.)
**The 7 pm reminder couldn't be set.**
The scheduler cap is already at its 20 limit, and there are already several `每天 19:00` reminders on your account — I can't add another without first disabling one of yours. Could you tell me which one you'd like me to replace? Easiest path: name any one of your existing 19:00 reminders and I'll re-purpose it to "复习错题本里今天到期的卡". Or, if you'd rather I just disable a duplicate one you don't use, say the word and I'll free up a slot.
Today's review list (25 cards due) is ready whenever you want to start — say "go" and I'll read you the prompts one at a time for self-test.
