Compensation is the process of reformulating an addition, subtraction, multiplication, or division problem to one that can be computed more easily mentally.
We will use compensation to find the difference of 30,000 and 6985.
Since, we have to evaluate 30,000 - 6,985
Let us add '15' to 6985,
6,985 + 15 = 7,000
Let us add '15' to 30,000
30,000 + 15 = 30,015
Now, we have to subtract 30,015 and 7,000
= 30,015 - 7,000
= 23,015
Therefore, the difference of 6,985 from 30,000 is 23,015.
