Possible death of calculators in education?

[pier4r]

What slide rule says is also useful. I remember when I had the first semester in calculus, I understood the integral and that's it. Anyway I just used the results given to say "the integral of this function, is this other function".

Then once I was walking and I "saw" how the integral of a certain class of functions was a certain class of other functions, it clicked. So sometimes we cannot get a certain understanding and we have to find a workaround, with memory for example.
