Estimate each of the following using general rule:
`730 + 998`

Answer

To estimate the sum of 730 and 998 using the general rule, we will follow these steps:

### Step 1: Round 730 to the nearest hundred.
- The number 730 is between 700 and 800. Since the tens digit (3) is less than 5, we round down.
- Therefore, 730 rounds to **700**.

### Step 2: Round 998 to the nearest hundred.
- The number 998 is between 900 and 1000. Since the tens digit (9) is 5 or more, we round up.
- Therefore, 998 rounds to **1000**.

### Step 3: Add the rounded numbers.
- Now we add the rounded numbers:
- 700 + 1000 = **1700**.

### Final Answer:
