I like making longer answers..
Okay.
So 952.
We put it onto a mountain like scale.
Over 50 you go rounding up
lower then 50 you go down..
at 50 you also round up
This also works with 10's, 50's, 100's, 1000's..
The list goes on.
But so if it's 952..
You round that up.
so the answer is 1000.
Just to show this strategy with another example lets use the number
If you were to round this number to the nearest 10 it's 520.
With hundreds it's rounded to 1000.
952 rounded to the nearest hundred is 1000.

97 rounded to the nearest hundred is 100. 97 rounded to the nearest ten is 100

952 rounded to the nearest hundred is 1000.

The answer is 800,000
853 rounded to the nearest 100: 900. 10853 rounded to the nearest 100: 10900.
