Explanation

According to the order of operations (BODMAS/PEMDAS - Brackets, Orders, Division/Multiplication, Addition/Subtraction):

  1. Division: 18÷3=618 \div 3 = 6
  2. Multiplication: 5×2=105 \times 2 = 10 The expression becomes: 6+10−46 + 10 - 4
  3. Addition: 6+10=166 + 10 = 16
  4. Subtraction: 16−4=1216 - 4 = 12 Thus, the correct value of the expression is 1212. Options A, C, and D are incorrect as they do not follow the proper order of operations.
