Hello everyone,
please it's very urgent! I need to program a calculator for tomorrow
I managed to do it but I still need to program the sign change button (+/-), the square root button, and the division by 0.
Please help me.

For changing the sign, you simply do
...onclick...
number=number*-1
for the square root it's here http://www.delphibasics.co.uk/RTL.asp?Name=Sqrt
regarding 0
If zero is divided, the result is always 0
if 0 is the divisor, it's an error
either you handle it with a try ... except
this is the case handled here http://www.delphibasics.co.uk/RTL.asp?Name=Except
otherwise simpler:
if divisor=0 then
exit
