Basics
- The Curta Calculator was a Soda Can size mechanical calculator
- It could do:
- Addition
- Subtraction
- Multiplication
- Division
- and to a certain degree with clever use, square roots, cubes, factors, and percentages
- This and a Slide Rule were some of the best tools of the time for number crunching
- All of this was done with no power
- Probably the most developed mechanical computer short of perhaps the Babbage Analytical Engine
- Also had the advantage of being more stable in enviroments such as a vehicle than slide rules
