-34,6-104,4=34,6+(104,4)=

To solve the expression \(-34.6 - 104.4 = 34.6 + (104.4)\), we can simplify it step by step.

1. First, let's clarify the operation and numbers:

   • We have \(-34.6 - 104.4\).

2. Combine the numbers:

   • \(-34.6 - 104.4 = -34.6 + (-104.4)\).

3. Now, add these two negative numbers:

   • \(-34.6 - 104.4 = -139.0\).

So the final result is: \[ -34.6 - 104.4 = -139.0 \]

The expression \(34.6 + (104.4)\) does not equal the first equation; it would equal \(34.6 + 104.4 = 139.0\).
