- Thousands Place: 1 × 1,000 = 1,000 (One thousand)
- Hundreds Place: 8 × 100 = 800 (Eight hundred)

How to Write 1800 on a Bank Cheque
To prevent legal disputes, banking errors, or fraudulent alterations when issuing a cheque for 1,800:
- Amount in Words Line: Write "One Thousand Eight Hundred Only". Adding "Only" at the end helps prevent unauthorized parties from adding extra amounts (such as "and fifty").
-
Amount in Numbers Box:
Write "1,800/-" or "$1,800.00".
The suffix
/-helps discourage extra zeros from being added to the amount. - Capitalization: Use title casing (One Thousand Eight Hundred Only) for clear and consistent presentation.
Grammar Rules: Hyphens and “And”
- Hyphens: Hyphens are only used for two-word compound numbers between 21 and 99 (such as twenty-one or ninety-nine). Writing "one-thousand" or "eight-hundred" is grammatically incorrect.
- The Word "And": In formal American English, "and" is reserved exclusively for the decimal fraction (e.g., "$1,800.50" becomes "one thousand eight hundred and 50/100"). In British English, "one thousand and eight hundred" is common in speech, but standard formal accounting omits the "and".
