*I like when a calculator has a paper-tape-style history in the
design. Then again, I use excel for math.* Giant piece of paper
full of thousands of calculators with embedded formulas.* But
when I'm on my phone, I'll use the calculator. When I had a
Minecraft server, one of my favorite plugins I put in was /CALC
/CALC 2*7 14 Perfect! :)
[and yeah I use Google search for math a lot.* They're great for
unit conversations.* Can't be beat! 270 m/h = ? km/s** Done.
