Arithma Addiator

My mom had one of these, I have either her old one or one just like it - she had hers in the 1950's or early 60's.

Found my Addiator that I used decades ago before cell phones and electronic calculators. Glad to find out again how it works.

Fascinating! Nice explanation, too (and, if I may add, you are role model for how hands should be manicured for close up videos! ;) Thank you for sharing this. Would be interesting to know how multiple carry overs work (e.g. 998+5)?

LOL I’m definitely not a role model regarding my hands but thanks. On the Arithma 5 carry overs and on the simulator 8. ( www.addiator.de/addiator_fla.htm )
