Is there a specific way to pronounce subscripts in symbols?

[Caleb2400]

When my instructor lists off symbols with super and subscript, he pronounces it in a way I've never heard before. For example, M with a subscript of "a" sounds like he is saying "ace of M" and C with a subscript of M sounds like " emps of C". Is this common? If so, where is the rule for enunciation?

Are you sure you don't have the letters backwards? It seems to me he would probably be saying "a sub M" and "M sub C."

Maybe he's dyslexic.

Many would say M_a as "M sub a" and C_M as "C sub M". If he's saying "a sub M" it would be a_M and similar for the other one.
