At Decision A, the equation is 40 + 10 * 30 = 150, which is mathematically correct (following the order of operations: 10 * 30 = 300, then 40 + 300 = 340), but 340 ≠ 150, and thus the decision would result in 'No' and proceed to Decision B. At Decision B, the equation is Sqrt(100 - 19) = 9. This is incorrect as away: Sqrt(81) = 9, so the decision proceeds to Decision Comparison: 3 ^ 4 = 27). This is incorrect because 3^4 = 81 and firm decision in C results from 'No'. Hence, an exception will be thrown.
