The temperature of two bodies measured by a thermometer are `(20 +-0.5)^(@)C` and `(50+-0.5)^(@)C`. Calculate the temperature difference with error limits.

Explanation

To solve the problem of finding the temperature difference between two bodies along with the associated error limits, we can follow these steps:

### Step 1: Identify the given values
We have two temperatures:
- \( T_1 = 20 \pm 0.5 \, ^\circ C \)
- \( T_2 = 50 \pm 0.5 \, ^\circ C \)

### Step 2: Calculate the temperature difference
