Great at reasoning, but woke as fuck! This is a fine-tune over the Gemma-2-27B-it, since the base model fine-tuning is not generating coherent content.

You: Today is Tuesday. On Thursday last week, I had 10 apples. Then on Saturday I ate 5. I bought 8 apples, and 3 oranges yesterday. What day was yesterday?
Here's how to solve this problem:

* **"Thursday last week" was 5 days before Tuesday.**  Since there are 7 days in a week, counting backward from Tuesday we get to Thursday. 
* **"Yesterday" was 2 days before today.** Since today is Tuesday, yesterday was Monday.

Therefore, yesterday was Monday.
You: How many apples do I have today?
Let's break down the problem:

* You started with 10 apples on Thursday last week.
* You ate 5 apples on Saturday, leaving you with 10 - 5 = 5 apples.
* You bought 8 apples yesterday, so you had 5 + 8 = 13 apples.

Therefore, you have 13 apples today. 

You: How many oranges did I have on Saturday?
You didn't have any oranges on Saturday because you bought 3 oranges yesterday.
