Question

Estimate the following using general rule:

$730+948$

Answer 1

Using the general rule of estimation,

Rounding off $730$ to the nearest hundreds = $700$
Rounding off $948$ to the nearest hundreds = $900$

Therefore, $730+948$ can be estimated as:
$=700+900$
$=1600$.

Note: There are multiple answers possible depending on your estimation to the nearest tens, hundreds or thousands. The estimate which is closest to the actual answer is the most meaningful answer.
