Question

Estimate the sum by rounding each number to the nearest thousand and adding
1,842+2,345

Answer 1

To estimate the sum of 1,842 and 2,345 by rounding each number to the nearest thousand:

1. Round 1,842 to the nearest thousand:
- 1,842 is closer to 2,000 than to 1,000, so it rounds to 2,000.

2. Round 2,345 to the nearest thousand:
- 2,345 is closer to 2,000 than to 3,000, so it rounds to 2,000.

Now, add the rounded numbers:

2,000 + 2,000 = 4,000

So, the estimated sum of 1,842 + 2,345, when rounded to the nearest thousand, is **4,000**.
