Solve: 2 × 5 ÷ 1 × 4 Using Order of Operations

Start by performing the multiplication and division from left to right according to the order of operations.

First, calculate the multiplication: $2 \times 5 = 10$

Next, divide the result by 1: $10 \div 1 = 10$

Finally, multiply by 4: $10 \times 4 = 40$

Thus, the correct answer is $40$.
