301.260:15-425:(112-87)•12

Interpret 301.260 as 301260 (dot as a thousands separator). Compute:

• 301260 ÷ 15 = 20084
• (112 − 87) = 25
• 425 ÷ 25 = 17
• 17 × 12 = 204

Then 20084 − 204 = 19880

Answer: 19880

Note: If 301.260 were meant as a decimal (301.260), the result would be different (-183.916). The likely intended interpretation is 301260.
