Explanation

### Step-by-Step Solution

1. **Definition of Order of Magnitude**:
- The order of magnitude is a way to describe the scale or size of a number in terms of powers of ten. It gives us a rough estimate of the size of a number by rounding it to the nearest power of ten.

2. **Understanding the Concept**:
- To determine the order of magnitude of a number, we express it in the form \( A \times 10^n \), where \( A \) is a number between 1 and 10, and \( n \) is an integer. The value of \( n \) represents the order of magnitude.
