Pronunciation: /ˌmʌl.tɪˈplɪ.sɪ.ti/ Explain

The multiplicity of a math object is the number of times the math object occurs in a context.[2] For example, in the prime factorization of 12 = 2 · 2 · 3 = 22 · 3, 2 appears twice, so it has a multiplicity of 2. 3 appears once, so it has a multiplicity of 1.
