The maths of 1234

1234 across cultures

• 1 (one): One means first and unique in most cultures; in Indian gift-giving an extra 1 (101, 501, 1001) turns a round sum into a fresh start.
• 2 (two): In Chinese tradition good things come in pairs, so doubled digits (22, 88) are favoured for weddings and openings.
• 3 (three): Three signals completeness in Western storytelling and is considered lucky in Korean tradition; in Hinduism it echoes the trimurti.
• 4 (four): In Chinese, Japanese and Korean, four sounds like the word for death, so many buildings skip fourth floors and buyers avoid 4s in phone numbers and plates.

1234 in business and commerce

• Ones read as 'first' and 'number one' — common in rankings, hotlines and brand names.
• Pairs suggest bundles and two-for-one offers.
• The 'rule of three' drives good-better-best pricing tiers.
• Remove 4s from prices, plates, room numbers and phone numbers aimed at East Asian buyers — it is one of the strongest number effects in commerce.
