Which spelling details matter here?
Compound numbers from 21 through 99 join the tens word and the ones word with a hyphen. In 55,555,555,554, the 54 part combines fifty and four, producing fifty-four. Hundreds are written by placing a digit word before hundred. In 55,555,555,554, the hundreds part is five hundred. American English usually omits and after hundred when more digits follow. That is why this page writes fifty-five billion five hundred fifty-five million five hundred fifty-five thousand five hundred fifty-four without adding and before the final part. English reads large numbers in three-digit groups. 55,555,555,554 reaches the billion group, so the group fifty-five is followed by the scale name billion. Scale names stay singular inside exact number names. English writes fifty-five billion without adding a plural s to the scale name.
