Thank you for taking the time to report this bug and helping to make Ubuntu better. I actually stumbled across this problem for other functions of the calculator a couple of times, but it is not a bug but intended behavior: To calculate a function "sin of something", "sqrt of something", or "1's complement of something" you have to *first* press the function and *then* enter the number. So your example should work if you first click on "1's" and then enter 1010. Most "real" scientific calculators work this way today. Please feel free to reopen this bug if this does not solve your problem or I misunderstood your report.
