Options

A. a. 47
B. b. 811.004
C. c. 35
D. d. 23

Answer

To solve the equation \( 840.003 - 5 - 23.999 \), we will follow these steps:

### Step 1: Subtract 5 from 840.003
First, we need to perform the subtraction of 5 from 840.003.

\[ 840.003 - 5 = 835.003 \]

### Step 2: Subtract 23.999 from the result
Next, we take the result from Step 1 and subtract 23.999 from it.

\[ 835.003 - 23.999 \]

To perform this subtraction, we can align the numbers:

```
835.003
- 23.999
```

Now, we subtract:

- Starting from the rightmost digit:
- \(3 - 9\) requires borrowing, so we take 1 from the next digit (0 becomes 9, and 3 becomes 13):
- \(13 - 9 = 4\)

- Next column:
- \(9 - 9 = 0\)

- Next column:
- \(5 - 3 = 2\)

- Next column:
- \(8 - 2 = 6\)

So, we have:

\[ 835.003 - 23.999 = 811.004 \]

### Final Answer
Thus, the final result of the calculation \( 840.003 - 5 - 23.999 \) is:

\[ \boxed{811.004} \]
