800000+ 5- 3000*8

To solve the expression \(800000 + 5 - 3000 \times 8\), follow the order of operations (PEMDAS/BODMAS):

1. Multiplication: Calculate \(3000 \times 8\): \[ 3000 \times 8 = 24000 \]

2. Addition and Subtraction: Now substitute this back into the expression: \[ 800000 + 5 - 24000 \] First, add \(800000 + 5\): \[ 800000 + 5 = 800005 \]

   Now subtract \(24000\): \[ 800005 - 24000 = 776005 \]

So, the final result is: \[ \boxed{776005} \]
