What is the result of 5 - 4 + 1.5 × 2?

The correct answer is: 4

To solve the expression 5 - 4 + 1.5 × 2, it’s important 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)). First, we handle the multiplication in the expression. The term 1.5 × 2 equals 3. Now, we can rewrite the expression with this result: 5 - 4 + 3. Next, we perform the operations from left to right. We start with the subtraction: 5 - 4 equals 1. Now the expression simplifies to: 1 + 3. Finally, we complete the addition: 1 + 3 equals 4. Thus, the result of the entire expression is 4, confirming that the answer aligns with the first choice. This thorough processing of the expression ensures clarity on how we arrive at the final result, emphasizing the necessity of following the order of operations in mathematical calculations.
