Figure presents a remarkable response from Claude. When describing the washing process of a product, the original text stated: "Before drying, the wet solid powder was immediately transferred to a 500-mL glass jar, and 400 mL of DMF was added. The jar was heated at 120 °C for 12 h, then cooled to room temperature. The DMF was decanted and replaced with 400 mL of fresh DMF. The jar was reheated at 120 °C, followed by decanting and replacing with fresh DMF. This was repeated four additional times." The total number of DMF washings was therefore 1 + 1 + 4 = 6, which Claude correctly calculated. This response highlights Claude's capacity to perform arithmetic reasoning and accurately interpret iterative procedures, which is crucial for understanding experimental protocols.
