Super helpful calculator

Thanks so much! Aaaalll the calculators in our lab are horribly half functioning, so this is really handy. The little side note area is handy too, because inevitably when I move from one bench to another or into the cell culture room real quick here and there I always leave my lab notebook in the previous spot. Unlike my notebook, this calc fits in my pocket so I can't forget it. No more napkin calculations for me! It erases too, so I can clear it once I put the calculations (more neatly at that!) In my notebook.
