How many perfect squares (squares of integers) are between -10000 and 10?

(i think it's four, but i'm not sure)

From NEGATIVE 10000 to 10 ? There are none between -10 000 and 0 (maybe you will say 0 is a perfect square)

from 0 to 10 there is 1 4 and 9 THREE ( or FOUR if you include ' 0 ' )

i did three and it was wrong, so i will try four

Keep me posted what you find.....
