2025:15•4(524+195):9+(308.308-207.207)•2

Interpretation (colon as division, dot as multiplication):

Expression: 2025 ÷ 15 × 4 × (524 + 195) ÷ 9 + (308.308 − 207.207) × 2

Compute step by step:

• (524 + 195) = 719
• 2025 ÷ 15 = 135
• 135 × 4 = 540
• 540 × 719 = 388,260
• 388,260 ÷ 9 = 43,140
• (308.308 − 207.207) = 101.101
• 101.101 × 2 = 202.202

Add: 43,140 + 202.202 = 43,342.202

Answer: 43342.202
