Solve Arithmetic Expression: $240 \div 8 \times 512 \div 4$

To solve the expression $240 \div 8 \times 512 \div 4$, we follow the order of operations (PEMDAS/BODMAS). Since there are only divisions and multiplications, we perform them from left to right.

Step 1: Perform the first division

Calculate $240 \div 8$.

$ 240 \div 8 = 30 $

Step 2: Perform the multiplication

Multiply the result from Step 1 by $512$. The expression is now $30 \times 512 \div 4$.

$ 30 \times 512 = 15360 $

Step 3: Perform the final division

Divide the result from Step 2 by $4$. The expression is now $15360 \div 4$.

$ 15360 \div 4 = 3840 $

Result

The final result of the calculation $240 \div 8 \times 512 \div 4$ is $3840$.
