How 8 is written
8 fills only the ones place, which is why its name, eight, is a single word.
Its ordinal form is eighth — only the final element takes the ordinal ending — and on a check the amount line reads "Eight and 00/100", where 00/100 stands for zero cents.
8 is 2 to the power of 3, so its binary form is a 1 followed by 3 zeros (1000) and its hexadecimal form is 8.
