Estimate the sum of 299 and 388

An estimate of the sum 299 + 388 would be 300 + 400. The answer is therefore around 700.

For this case we have the following numbers:

299

388

Let's round up each of the numbers to the nearest hundred,

We have then:

299 = 300

388 = 400

We note that now we have two numbers whose approximation is easier to add.

We have then:

300 + 400 = 700

Answer:

The sum of 299 + 388 is approximately:

700
