400:8+50-24*2

To solve the expression \( 400:8 + 50 - 24 \times 2 \), we follow the order of operations (PEMDAS/BODMAS):

1. Division and multiplication from left to right:

   • \( 400 \div 8 = 50 \)
   • \( 24 \times 2 = 48 \)

2. Now substitute these values back into the expression: \[ 50 + 50 - 48 \]

3. Now perform addition and subtraction from left to right:

   • \( 50 + 50 = 100 \)
   • \( 100 - 48 = 52 \)

So, the final result is \( 52 \).
