You wouldn't believe... but I was actually bad in in-the-head calculations until it has come to numerical methods and programming. Then I had to buy a good pocket calculator (about $50 at the time... not cheap, considering that this was 30 years ago) and type hundreds of operations to see my calculation method works. Of course, technology made this knowledge obsolete - most of the things we did then are nowadays part of Excel or any decent compiler, so almost nobody writes calculational code at that level, but hey, someone has to know how that works.

Anyway, it seems to be I was the lazy programmer even before I learned programming - I soon started calculating a few things in my head, because it was easier than typing. And that's when I learned to do these things mentally. Contrary to the common wisdom saying your brain will forget how to do it as soon as you start relying on machines.
