Yep. I force memorized so many calculations because our teachers constantly told us that in the future we wouldn't always have a calculator with us. It was helpful, I got pretty far along in collegiate math without tutors or assistance thanks to the hard calculation skills I drilled into my head. But, counterpoint, if I leave my calculator/computer/all in one everything device at home on any given day it can ruin my entire day. I haven't gone 72 hours without a calculator in nearly a decade.
