How the hundreds part works

Hundreds are written by placing a digit word before hundred. In 400,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, the hundreds part is four hundred.

How the novemdecillion group is read

English reads large numbers in three-digit groups. 400,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 reaches the novemdecillion group, so the group four hundred is followed by the scale name novemdecillion.

Why scale names stay singular

Scale names stay singular inside exact number names. English writes four hundred novemdecillion without adding a plural s to the scale name.

Why zero groups are skipped

When a three-digit group is 000, English skips that group in the word form. This keeps four hundred novemdecillion shorter and easier to read.
