Standard Form Up to 5-Digits Sheet 2: Convert numbers from expanded form to standard form.

Problem Overview:

The task is to convert numbers described in expanded form (using words like "thousands," "hundreds," "tens," and "ones") into their standard numerical form. The example provided is:

- Example: 7 ten thousands + 3 thousands + 18 tens = 73,180

We need to follow the same process for each of the given problems.

---

Solution Approach:

1. Identify the place values:
- "Ten thousands" corresponds to the 5th digit from the right.
- "Thousands" corresponds to the 4th digit from the right.
- "Hundreds" corresponds to the 3rd digit from the right.
- "Tens" corresponds to the 2nd digit from the right.
- "Ones" corresponds to the 1st digit from the right.

2. Convert each component:
- Multiply the coefficient by the corresponding place value.
- Sum all components to get the final number.

3. Handle special cases:
- If a component exceeds its place value (e.g., 18 tens), break it down into higher place values (e.g., 18 tens = 1 hundred + 8 tens).

4. Write the final number in standard form.
