Here's why:
* Consonants are sounds: They are part of the phonetic system of language, how we make sounds with our mouths.
* Numbers are abstract concepts: They represent quantities and are used for counting, measuring, and other mathematical operations.
Possible Misunderstandings:
It's possible you're thinking of one of these:
* Numerology: This is a belief system that assigns meaning to numbers based on their position, combination, etc. It's often connected to astrology and esoteric ideas. There might be systems within numerology that associate certain numbers with letters (and thus, sounds) but this is unrelated to formal mathematics.
* Phonetic Transcription: In phonetics, we use symbols to represent speech sounds. Some symbols may look like numbers, but they are representing sounds, not numbers themselves.
