If '+' means '-', '-' means 'x', 'x' means '÷' and '÷' means '+', then what will come in place of the question mark (?) in the following equation?

13 - 780 x 12 ÷ 16 + 32 = ?

Correct Answer

829

[Symbol Substitution Strategy]: We must precisely swap out the original operators according to the specified cipher. The expression transforms into 13 × 780 ÷......

💡 Analysis & Explanation

[Symbol Substitution Strategy] ▼

We must precisely swap out the original operators according to the specified cipher. The expression transforms into 13 × 780 ÷ 12 + 16 - 32.

[BODMAS Execution Flow] ▼

Commencing with the division segment, 780 divided by 12 equals 65. The expression simplifies to 13 × 65 + 16 - 32.

[Multiplication and Addition Phase] ▼

Next, evaluating the product of 13 and 65 gives 845. Adding 16 to this product yields 861.

[Final Resolution] ▼

Completing the sequence with the subtraction operation, 861 minus 32 evaluates exactly to 829.

Conclusion ▼

The correctly simplified mathematical value is 829.
