### Find the sum 389 + 871 =

Explanation
The sum of 389 and 871 is calculated by adding the corresponding digits in each place value. Starting from the rightmost digit, 9 plus 1 equals 10, which is written as 0 in the ones place and carry over the 1 to the tens place. In the tens place, 8 plus 7 plus the carried over 1 equals 16, which is written as 6 in the tens place and carry over the 1 to the hundreds place. Finally, in the hundreds place, 3 plus 1 equals 4. Therefore, the sum of 389 and 871 is 1260.

### Find the difference702 - 568 =

Explanation
The correct answer is obtained by subtracting 568 from 702. When we subtract the units place, 2-8, we get -6. Since we cannot have a negative value in the units place, we borrow 1 from the tens place. In the tens place, 0-6 becomes -6 but with the borrowed 1, it becomes -5. Finally, in the hundreds place, 7-5 is 2. Therefore, the difference between 702 and 568 is 134.

### 578 – 234 = ?Round to the nearest 10 to estimate the answer.

Explanation
To round 578 to the nearest 10, we look at the digit in the tens place, which is 7. Since 7 is greater than or equal to 5, we round up to the next multiple of 10, which is 580. To round 234 to the nearest 10, we look at the digit in the tens place, which is 3. Since 3 is less than 5, we round down to the previous multiple of 10, which is 230. Subtracting 230 from 580 gives us 350. Therefore, the estimated answer to 578 - 234 rounded to the nearest 10 is 350.
