Question

Estimate and compare with the actual sum:

$9864+2349$

Answer 1

Step-1: find the estimated values of both the numbers:

estimated value of $9864$ on rounding off to its nearest thousands= $10,000$

estimated value of $2349$ on rounding off to its nearest thousands= $2000$

Step-2: find the estimated sum-

$\Rightarrow 10000+2000+12,000$

Step-3: find the actual sum-

$\Rightarrow 9864+2349=12213$

Step-4: to compare both the values, find their difference-

$\Rightarrow 12213-12000=213$

Hence, the above is the required estimation and comparison.
