```Hello,

Thank you for the email about the tutorial. I have been using it extensively in my learning of nemeth code. In there, only subscripts in subscripts and superscripts in superscripts are talked about, but not the combination of the two. I wasn’t sure if that meant it is not possible to do.

Thank you,
Nicholas

The only thing I have run into that I have had a hard time figuring out is putting superscripts in subscripted material, putting subscripts in superscripted material, and putting summations in superscripted material. For example, I have tried to do something like M sub X squared with x squared being in the subscript. I use dots 134 for M, dots 56 for starting the subscript, dots 1346 for X, dots 45 for the start of the subscript, dots 23 for 2, and dot 5 to go to the baseline. I get the squared term on the M. An example for superscripts is when I have e exponent the sum from i equals one to n of x sub i. I put e, dots 15, exponent, dots 45, the usual summation order of dots, dot 5 dots 46 dot 6 dots 234 dots 146 dots 24 braille space dots 46 dots 13 braille space dot 2 dots 126 dots 1345 and dots 12456, dots 1346 for X, dots 56 for subscript, dots 24 for i, and then dot 5. I get different errors about parentheses or superscripts and subscripts not being closed. My last example is e exponent X sub one end sub plus X sub 2 end sub and so on all in the exponent. I have tried the usual things for superscripts and subscripts, but get similar answers to the errors in the previous example. Are these things I am trying to do possible to do in nemeth code? If so, how would they be done?
