5,6-3,04•37,1-2,09

To solve the expression \( 5.6 - 3.04 \cdot 37.1 - 2.09 \), we should follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). 1. **Calculate the multiplication first**: \[ 3.04 \cdot 37.1 = 112.144 \] 2. **Now substitute that back into the expression**: \[ 5.6 - 112.144 - 2.09 \] 3. **Perform the subtraction from left to right**: \[ 5.6 - 112.144 = -106.544 \] Then: \[ -106.544 - 2.09 = -108.634 \] So, the final result is: \[ \boxed{-108.634} \]
