Explanation

According to the order of operations (BODMAS/PEMDAS):

  1. Multiplication and Division are performed before Addition and Subtraction. 2×6=122 \times 6 = 12 10÷5=210 \div 5 = 2 The expression becomes: 15−12+215 - 12 + 2
  2. Perform Addition and Subtraction from left to right. 15−12=315 - 12 = 3 3+2=53 + 2 = 5 Therefore, the correct answer is 5. Options 26, 17, and 3 are incorrect as they result from not following the correct order of operations.
