Soroban (Japanese abacus)

Soroban of 13 columns. For the curious, I refer to Wikipedia which will explain much better than me ^^. All I can say is that it's great to approach arithmetic in a different way for children and for adults it's a fun way to get up to speed. The Wikipedia link: https://fr.wikipedia.org/wiki/Soroban If you search on Google, you will find a lot of sites and videos explaining how it works. Once you understand the logic, it's great. Sometimes even faster than getting the calculator on your smartphone. All you'll need are 3mm diameter metal rods. Personally, I used this reference (https://www.amazon.fr/gp/product/B00NQCNBX2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1)
