To evaluate the expression \(9 - 14 \div 2 + 3 \times 4\), 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 and Multiplication** (from left to right):<br /> - \(14 \div 2 = 7\)<br /> - \(3 \times 4 = 12\)<br /><br /> Now the expression is:<br /> \[<br /> 9 - 7 + 12<br /> \]<br /><br />2. **Addition and Subtraction** (from left to right):<br /> - \(9 - 7 = 2\)<br /> - \(2 + 12 = 14\)<br /><br />So, the value of the expression \(9 - 14 \div 2 + 3 \times 4\) is \(\boxed{14}\).
