To solve the expression 5 + 3 × 4 - 2, you need to follow the order of operations, which is often remembered using the acronym PEMDAS:
1. Parentheses: Perform any calculations inside parentheses first. There are no parentheses in this expression, so we move to the next step.
2. Exponents: Evaluate any exponents. There are no exponents in this expression.
3. Multiplication and Division: Perform any multiplication or division from left to right.
In this case, there is multiplication involved: 3 × 4. Multiply 3 by 4 to get 12.
4. Addition and Subtraction: Perform any addition or subtraction from left to right.
In this case, we have 5 + 12 - 2. Add the numbers: 5 + 12 = 17. Then, subtract 2 from 17 to get the final answer.
So, the correct way to solve this expression is:
5 + 3 × 4 - 2 = 17 - 2 = 15
Therefore, the correct answer is 15, not 15.
