六

1. Origins, structure, and basic meaning

• Structure: 六 (ろく) is the numeral six. 番号の六 identifies a written number, while 六になる gives the result of a calculation.
• Basic usage: One example selects and marks the number six; the other states that multiplying three by two produces six.

2. Common pitfalls and similar expressions

• Six as an identifier and six as a result
  • 番号の六 is a nominal reference to a label, whereas 六になる predicates a resulting value. Reading ろく should remain distinct from the counter-like form 六つ.
