To determine how many years ago the Chinese used red and black calculating rods in 300 B.C., we can subtract 300 from the current year. Let me find out the current year and calculate the answer for you.
- Current year: 2022
- Calculation: 2022 - 300 = 1722
Therefore, the Chinese used red and black calculating rods approximately 1,722 years ago.
