Estimate the following sum to the nearest thousands.
`3940 + 1850`

Answer

To estimate the sum of 3940 and 1850 to the nearest thousand, follow these steps:

### Step 1: Add the two numbers
First, we need to find the actual sum of 3940 and 1850.

3940 + 1850 = 5790

### Step 2: Identify the place value
Next, we need to look at the digit in the thousands place of the sum we just calculated (5790). The thousands place is the first digit from the left, which is 5 in this case.

### Step 3: Check the next digit
Now, we check the digit in the hundreds place, which is the next digit to the right of the thousands place. In 5790, the hundreds place digit is 7.

### Step 4: Determine if we round up or down
Since the hundreds place digit (7) is greater than 5, we will round up the thousands place digit (5) by 1.

### Step 5: Write the estimated sum
After rounding, we change the thousands place from 5 to 6, and all other digits to the right become 0. Therefore, the estimated sum to the nearest thousand is:

6000

### Final Answer
The estimated sum of 3940 + 1850 to the nearest thousand is **6000**.
