I've run into a situation where I wonder if we have been brailling it correctly. In Nemeth Rule V §32d it is stated "When a type-form indicator is used with numerals only, it is effective until terminated by a space, a numeric indicator, or any non-numeric symbol.”

This is where my quandary lies. Does an operation sign qualify as a non-numeric symbol?

Here is an example from one of my books:

*3*●*3*●2 = 18

Here are the two ways we see to braille it:

.#3*.#3*#2 .k #18 or

.#3*3*#2 .k #18

Now if the rule is interpreted as the operation sign being a non-numeric symbol would it be brailled as follows:

.#3*.#3*2 .k #18

Please give us any guidance you feel is appropriate to understand the proper way to emphasize this example.

Thanks!
