To take the square root of 625, the calculator would multiply by 5 to yield:
3125
Then it would start subtracting 100s+5 100s+15... from the leftmost digits: (s started at 0)
3125
500-
1500- : 2 subtractions so first digit is 2 (so s is now 2)
leaving 1125
Then it subtracted 100s+5, 100s+15... (s = 2)
1125
205-
215-
225-
235-
245- : 5 subtractions (so d is 5 which is appended to s yielding 25)
leaving 0
So the root of 625 is 25.

In this case, you can take the square root by chopping off the first digit: remove the 6. The result is 25. To what other 3 or 4 digit numbers can you do this to?
Also, to take the square root of 141,376, chop off the 141. The result is 376, which is correct.
PS. I forgot to mention. -25 is also a square root of 625.
