Estimate the difference `(673-258)` to the nearest hundred.

Answer

To estimate the difference \(673 - 258\) to the nearest hundred, we will follow these steps:

### Step 1: Round off 673 to the nearest hundred.
- Look at the tens digit of 673, which is 7.
- Since 7 is greater than 5, we round up.
- Therefore, \(673\) rounds to \(700\).

### Step 2: Round off 258 to the nearest hundred.
- Look at the tens digit of 258, which is 5.
- Since 5 is equal to 5, we also round up.
- Therefore, \(258\) rounds to \(300\).

### Step 3: Calculate the estimated difference.
- Now we subtract the rounded numbers:
\[ 700 - 300 = 400 \]

### Final Answer:
The estimated difference of \(673 - 258\) to the nearest hundred is \(400\).
