Let's calculate the sum first:
- Add the numbers together:
\[ 365 + 925 + 3.698 + 7.299 + 2.520 \]
Calculating step by step:
- \(365 + 925 = 1290\)
- \(1290 + 3.698 = 1293.698\)
- \(1293.698 + 7.299 = 1300.997\)
- \(1300.997 + 2.520 = 1303.517\)
Now we subtract 10,000 from the sum:
\[ 1303.517 - 10,000 = -8696.483 \]
Therefore, the result is:
\[ \boxed{-8696.483} \]
