 Thank you very much  for your reply.

Yes I malready did what you said.

The photo that I (try) to upload.You can see what I mean.

For example i did some basic calculations, for instance 56+65 hit enter ok it gave me solution.

or 5^2 it gave me answer at blue line.

but when I try to write X^2+5-2 I hit the enter but nothing it gave me.

And I get the last update already.

Thanks in advance.
