The value of \(25.3 \times 5 - 35 \div 5 - 3 \times 18.5\) is :
Answer: B
The value is 64.0.
By the order of operations, carry out multiplication and division first, then subtraction from left to right:
\[ \begin{aligned} 25.3 \times 5 &= 126.5 \\ 35 \div 5 &= 7 \\ 3 \times 18.5 &= 55.5 \\ 126.5 - 7 - 55.5 &= 64.0 \end{aligned} \]
Working strictly from left to right, ignoring the order of operations, gives 283.05 (126.5, then 91.5, 18.3, 15.3 and finally 15.3 × 18.5), which is the trap in option 1.
