I remember my friend, Sarah, learning how to use a slide rule as a project in math when we were younger. I had never heard of the Addiator, though. Much less, seen one.
This find comes to us from my friend and colleague Melissa. When I told her I had finally started my second blog, after years of wanting to, she immediately mentioned this find that her friend had stumbled upon and snatched up (no Thrift Regret here!) Luckily Melissa and her friend were happy to share the find with us. I love some of the instructions that you can read in the photo. Made of long lasting metal!
