When estimating the value of 1573 + 1211 - 697, which is the closest approximation?

To estimate the value of the expression 1573 + 1211 - 697, it's useful to round each number to the nearest hundred for simpler calculations.

Starting with 1573, rounding it to the nearest hundred gives approximately 1600. For 1211, rounding it to the nearest hundred results in around 1200. Finally, rounding 697 gives approximately 700.

Now, substitute these rounded values into the expression:

1600 + 1200 - 700.

Adding 1600 and 1200 results in 2800. Then, subtracting 700 gives:

2800 - 700 = 2100.

This rounded calculation shows that the closest approximation to the original expression is indeed 2100. Using these estimated values simplifies the operation while still providing a meaningful result close to what the actual calculation would yield.
