I no longer have the access I used to have to observe trends in mathematical education, but I think they still teach mathematical operations.
Also, skill is required to set up a problem reasonably even if you have a calculator capable of solving it.
And finally, supposedly, kids are being taught to tell whether the answer they get makes sense. If they should be getting an answer in the millionths and get one in the millions, hopefully they'll have enough numerical sense to recognize it's off.
