Correct answer and explanation

Correct answer: 15

Explanation: ✅ Correct Answer: C) 15 📚 Explanation: Substituting the new mathematical operations into the expression transforms it into: $7 + 10 \div 5 \times 6 - 4$. Following the standard order of operations (BODMAS), we calculate the division first: $10 \div 5 = 2$. The expression becomes $7 + 2 \times 6 - 4$.
