Completed

A finished reasoning trace with its recorded duration. Collapsed by default once thinking has ended — expand to read the trace.

Streaming

While the model is thinking the panel shimmers and auto-opens; it closes itself a beat after streaming ends. Press replay to watch the cycle.

Let me work through this step by step.

The user wants the total after a 15% discount on £240. First I'll compute the discount: 15% of 240 is 36. Subtracting that from 240 leaves £204.

I should double-check: 240 × 0.85 = 204. That matches, so the answer is £204.
