If `L = 2.06 cm +- 0.02 cm`
`B = 1.11 cm +- 0.03 cm`
What are (L + B) and (L - B) equal to ?

Explanation

To solve the problem, we need to find the values of \( L + B \) and \( L - B \) along with their associated uncertainties.

**Step 1: Identify the values and uncertainties**
- Given \( L = 2.06 \, \text{cm} \pm 0.02 \, \text{cm} \)
- Given \( B = 1.11 \, \text{cm} \pm 0.03 \, \text{cm} \)

**Step 2: Calculate \( L + B \)**
- First, we add the values of \( L \) and \( B \):
