⚖️ UCC § 3-114 Statutory Check Supremacy
Under Section 3-114 of the Uniform Commercial Code (UCC), when words and numbers are in conflict on a check, draft, or promissory note, written words legally govern over numerical digits. Anti-fraud bounding asterisks (e.g. *** Exact Sum of ... Only ***) and safety trailing fill lines are specifically engineered to defeat "check washing" and pen addition alterations.
🇬🇧 British English 'And' vs. 🇺🇸 American Direct Syntax
British English strictly mandates the conjunction "and" between hundreds and subsequent tens/units (e.g. "One hundred and twenty-five"). In contrast, standard American English typography and commercial manuals recommend omitting "and" (e.g. "One hundred twenty-five") to avoid conflating the spoken word with decimal fractions.
📚 Chicago Manual of Style (CMOS) vs. AP Stylebook
The Chicago Manual of Style (CMOS) dictates spelling out numbers from zero through one hundred in general prose (as well as round multiples of hundreds, thousands, and millions). The Associated Press (AP) Stylebook mandates spelling out single-digit whole numbers one through nine, using numerals for 10 and above. Both authorities require compound numbers between 21 and 99 to be hyphenated (e.g., twenty-four, seventy-five).
