In contracts numbers are usually written twice: in numerical and literal form.
I understand the vast majority of text in a typical contract can be safely deleted without impacting the core message due to the typical insane amount of repetition and unnecessary verboseness, but I don't really understand what's the point of writing some (not even all) numbers twice.
For example:
You agree to these Terms of Use on
behalf of yourself and, at your
discretion, for one (1) minor child
for whom you are a parent or guardian
and whom you have authorized to use
the account you create on the Service.
It's very inconsistent, sometimes they appear in only numerical form:
[…] WOULD CONSTITUTE A VIOLATION OF SECTIONS 1, 2 OR 9.
Sometimes only literal:
[…] includes two components […]

Its done to make any tempering with the document difficult. Maybe one can change the number in one place but it wont be easy reflecting the change in the other representation
