Which of the following is the correct Simplification of the expression below? 12 +3 X 4 -1+ 2^3

Rationale

31 is the correct simplification of the expression 12 +3 X 4 -1+ 2^3.

The expression needs to be solved following the order of operations, also known as BIDMAS/BODMAS/PEDMAS, which stands for Brackets, Indices (or Orders or Exponents), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

A (31) CORRECT

This is the correct answer. Following the order of operations, we first calculate the exponent 2^3 to get 8. Then we multiply 3 by 4 to get 12. Adding these results along with the 12 gives us 32, subtracting 1 from which gives us the final answer of 31.

B (7) YOUR ANSWER

This answer might be obtained if we perform all operations from left to right without following the order of operations. However, this is incorrect as multiplication and exponents should be performed before addition and subtraction.

C (15) YOUR ANSWER

This answer would be the result if we incorrectly perform the operations from right to left, rather than following the order of operations.

D (101) YOUR ANSWER

It's unclear how this answer might be obtained from the given expression, as performing the operations in any order should not yield such a high number. This answer is incorrect.

Conclusion

The correct simplification of the expression 12 +3 X 4 -1+ 2^3 is 31. This is obtained by correctly following the order of operations: first performing the exponent, then multiplication, and finally addition and subtraction from left to right. The other options may result from incorrect application of the order of operations.

Which of the following is the correct Simplification of the expression below? 12 +3 X 4 -1+ 2^3

31 is the correct simplification of the expression 12 +3 X 4 -1+ 2^3.
