0o7222 is an octal number, a numeral system that uses eight distinct digits, ranging from 0 to 7. In this system, each digit represents a power of eight, with the rightmost digit representing 8^0 (1 in decimal), the next digit to the left representing 8^1 (8 in decimal), and so on.

The number 0o7222 is composed of four digits. The leftmost digit is 7, which represents 7 * 8^3 (7 * 512 in decimal), the next digit is 2, representing 2 * 8^2 (2 * 64 in decimal), followed by another 2, representing 2 * 8^1 (2 * 8 in decimal), and the last digit is 2, representing 2 * 8^0 (2 * 1 in decimal).
