Definition of Senary
Senary numbers are made up only of the digits \(\{0,1,2,3,4,5\}\). Each place in a senary number corresponds to a power of \(6\).
Because there are only \(6\) different possible digits in a Senary number, we also call them Base \(6\) numbers.
For example, the senary number \(1205\) is equal to the decimal number \(1 \times 6^3 + 2 \times 6^2 + 0 \times 6^1 + 5 \times 6^0 = 216 + 2 \times 36 + 0 + 5 = 293\).
Some other examples of Senary numbers are:
- \(55\), which corresponds to the decimal number \(35\).
- \(500\), which corresponds to the decimal number \(180\).
- \(101\), which corresponds to the decimal number \(37\).
