Follow the BODMAS rule strictly (Division, Multiplication, Addition, Subtraction) after replacing symbols; calculate from left to right as per BODMAS sequence.
Follow the BODMAS rule strictly (Division, Multiplication, Addition, Subtraction) after replacing symbols; calculate from left to right as per BODMAS sequence.
Substitution
Replace the given letters with their arithmetic operations: 207 D 14 B 6 C 105 A 5 becomes 207 - 14 * 6 + 105 / 5.
Application of BODMAS
First, solve division: 105 / 5 = 21. Equation becomes 207 - 14 * 6 + 21. Next, solve multiplication: 14 * 6 = 84. Equation becomes 207 - 84 + 21.
Final Calculation
Perform addition and subtraction: 207 - 84 = 123. Then, 123 + 21 = 144.
A: 183 is incorrect because it ignores the multiplication/division order, C: 168 is incorrect due to a calculation error in the subtraction step, D: 165 is incorrect because it fails to apply the division operation correctly first.
B is correct because replacing the symbols and applying the BODMAS order of operations results in 207 - 84 + 21, which equals 144.
Always perform Division and Multiplication first from left to right, followed by Addition and Subtraction; never proceed linearly without checking for priority operations.
