To evaluate the expression \(25 \div 5 + 2 \times 8 + 5\), we need to 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)).<br /><br />1. **Division**: Perform the division first.<br /> \[<br /> 25 \div 5 = 5<br /> \]<br /> So the expression now is:<br /> \[<br /> 5 + 2 \times 8 + 5<br /> \]<br /><br />2. **Multiplication**: Next, perform the multiplication.<br /> \[<br /> 2 \times 8 = 16<br /> \]<br /> So the expression now is:<br /> \[<br /> 5 + 16 + 5<br /> \]<br /><br />3. **Addition**: Finally, perform the addition from left to right.<br /> \[<br /> 5 + 16 = 21<br /> \]<br /> \[<br /> 21 + 5 = 26<br /> \]<br /><br />Therefore, the value of the expression \(25 \div 5 + 2 \times 8 + 5\) is \(\boxed{26}\).
