Question

What sound maps to the digit 3, and what's the memory hook?

Answer

3 = the /m/ sound (m).

Hook: A lowercase m has three downstrokes. Example: home (3), mummy (33).

Question

Why can the letter c stand for two different digits — as in "ice" versus "cat"?

Answer

Because c has no sound of its own: soft c sounds like /s/ (0), hard c sounds like /k/ (7).

  • ice → the c is soft, /s/ → 0.
  • cat → the c is hard, /k/ → 71.

This is the "sound not spelling" rule in miniature. The same trap applies to g (soft "gem" = 6 vs hard "goose" = 7) and to s (hissy "sun" = 0 vs buzzy "daisy", where s sounds /z/, still = 0). Say the word aloud and let your ear pick the digit.
