Answers to Questions (FAQ)
How to count using the tally marks unary system?
The unary system based on successive marks consists of recording each addition of n units by n marks (generally lines, bars or sticks). The system uses a single symbol (the system is said to be unary) and allows the count to be updated (for numbers up to a few tens, beyond that, the system is neither practical nor efficient).
The use of tally marks is to group each set of 5 to facilitate counting
