Let's solve the problems step by step:

### 14) Round each decimal to the nearest whole number. Estimate the difference between 82.35 and 71.94.
- **82.35** rounds to **82**.
- **71.94** rounds to **72**.
- The estimated difference is:
  \[
  82 - 72 = 10
  \]

### 15) Round -52.13 and -20.26 to the nearest ten, and then estimate the product.
- **-52.13** rounds to **-50**.
- **-20.26** rounds to **-20**.
- The estimated product is:
  \[
  -50 \times -20 = 1000
  \]

### 16) Round each decimal to the nearest whole number. Estimate the quotient of 90.44 and -29.55.
- **90.44** rounds to **90**.
- **-29.55** rounds to **-30**.
- The estimated quotient is:
  \[
  \frac{90}{-30} = -3
  \]
