How 16 is written
16 is the sum of its place values, 10 + 6, and is written sixteen.
Its ordinal form is sixteenth — only the final element takes the ordinal ending — and on a check the amount line reads "Sixteen and 00/100", where 00/100 stands for zero cents.
The last part is not built from its digits: English names 10 to 19 with single irregular words, so this is sixteen, never ten six.
16 is 2 to the power of 4, so its binary form is a 1 followed by 4 zeros (10000) and its hexadecimal form is 10.
