\( ( \sum ( 51,75 - 25,4 ) ) + 25,4 \times 3 \)

To break it down, first calculate \( 51,75 - 25,4 \) which equals \( 26,35 \). Since there is a sum symbol here, we can treat it as just a straightforward addition, thus \( \sum ( 26,35 ) \) translates to simply taking that value. Now, for the second part: \( 25,4 \times 3 = 76,2 \). Adding these together gives us \( 26,35 + 76,2 = 102,55 \). So, the final answer is \( 102,55 \)! If you put this in context, calculations like these are commonly used in budgeting or financial projections. Understanding how to break down complex formulas helps in managing personal finances or even business-related expenses effectively. Moreover, many people often skip organizing their steps in mathematical problems, leading to confusion or errors. Always lay out each component clearly, and verify each operation as you go; it can save you from pesky mistakes and ensure a smoother calculation process!
