23,4-1,8-14,6

Ответ: 7

Answer 3

Let's solve the expression step by step:

1. Start with the parentheses: -(-5.6 + 7.4) = -(1.8) = -1.8 -(13.5 - 1.1) = -(12.4) = -12.4

2. Now, the expression becomes: 23.4 - (-1.8) + (-12.4)

3. Continue with the subtraction inside the parentheses: 23.4 + 1.8 + (-12.4)

4. Finally, perform the addition: 25.2 + (-12.4) = 12.8

The result of the expression is 12.8.
