```Hello,

Thank you for the help. I did those three examples over again with your suggestions Sarah and the output is much improved. I played around with it a bit to get some other little things to work. For the first example, m sub x squared end sub, right now I have m, dots 45, x, dots 45, dots 56, 2, dots 56, plus, x, dots 45, dots 56, 3, dot 5, start parenthesis, t, and end parenthesis. Right now the result has 2 plus x3 in the superscript of the first x in the subscript. I was trying to make m sub x squared plus x cubed end sub. How would I fix this?
For the second example, e exponent the sum from i equals 1 to n of x sub i end sub end exponent, I have e, dots 56, dots 46, dot 6, s, dots 45, dots 56, i, space, dots 45, dots 56, dots 46, dots 13, space, dots 45, dots 56, 1, dots 45, dots 45, n, space, dots 45, x, dots 45, dots 56, and i. The cells after the last space is where I am trying to fix. Before, the x sub i was on the baseline. I was trying to put it in the exponent next to the summation, but am getting errors now. Is there something in it that is missing?
For the third example, which is e exponent x sub i end sub plus x sub two end sub end exponent, I have e, dots 56, x, dots 56, dots 45, 1, dots 45, plus, x, dots 45, dots 56, and 2. I am getting an error for example 2 and 3 that says “Double subscripts. Use braces to clarify.” I tried that, but it put the second set of subscripts or superscripts on the parenthesis. Is there a way to fix this error?
For the rules of Nemeth Code, is there a good place to find all of them?

Thank you,
Nicholas

Phew!

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?
