You've uploaded a worksheet containing
decimal addition and subtraction problems, arranged in 4 rows with 6 problems each (24 total). All values are in dollars, so we’ll treat them as decimal numbers and compute each operation carefully.
---
✔ Solution Strategy:
We will solve each problem one by one, aligning decimals properly and performing the arithmetic. Since these are money amounts, we’ll keep two decimal places in all answers.

## 📝 Explanation Summary:
- All operations involve
adding or subtracting decimal numbers (dollars and cents).
- We aligned the decimal points vertically for accuracy.
- When adding, we carried over if needed; when subtracting, we borrowed if necessary.
- All results are rounded to
two decimal places, as required for currency.
- This type of practice helps reinforce
decimal place value and
real-world math applications like handling money.
