I guess the soroban is by far the simplest calculating machine before the first digital calculator appeared. Yet, the oldie but goodie soroban is still used today for its numerous benefits. (I have one myself) • Fosters a greater sense of numbers. • Helps develop an intuitive understanding of numbers through their concrete representation on the soroban (similar to Roman numerals). • Fosters one's trust in the process of calculation by enabling one to observe it in action. • Manifests the concept of decimal places and the progression of units by tens physically. • Instantly accomplishes addition and subtraction when numbers are placed on the abacus. • Improves understanding of compounded numbers (through the use of supplementary numbers for 5 and 10). • Helps in developing the beneficial qualities of concentration, patience, and endurance. • Fosters one's confidence in calculation. • Uses a left to right calculation method, which makes quick estimation and rounding off possible. • Works on the decimal rather than fractional system, an easy progression to digital systems. • Develops mental calculation, which is the ultimate resource. • Develops the right brain tremendously. • Leads to greater mental capacity. • Expresses large numbers simply and easily. • Provides a sense of achievement as one's proficiency improves.
I have an arithmometer (four operation digital calculating machine) patent 1850 and it works with negative numbers, unlike this "roman" abacus, but like a real roman abacus.
Hi Joe, What a GREAT Video ! Thank You SO Very Much ! Warm Regards, Michael Vannozzi
I have never saw a cooler abacus than that one. It is amazing and I want one
Wow, that's a handsome calculator there :D

Well stated!

I wasn't aware that the Romans were "Bronze Age". 🤔
Iron age, certainly, but whatever. This piece is great.
