So as your (robert) earlier post, subscript is to represent a letter, not a variable. So how abt this second question? 2) So my final conclusion is it is better to use: Ax or A_x to represent A subscript x as everyone does? Because i thought to represent equations 100% symbolically. It is not necessary, but then isn't that one of the strengths of Maple? AKS.

Hi, 1) What i was testing was to use: sum(f,i=k..n); and my function contains a subliteral to represent subscripts. So i was expecting it to sum my function according to x with subscript of i. Example: sum(`#msub(mi("x"),mi("i",fontstyle = "normal"))`, i = 0 .. 1) I thought the result to be x subscript 1 plus x subscript 2. but i return 2*x subscript i. (Correct me if i am wrong) 2) So my final conclusion is it is better to use: Ax or A_x to represent A subscript x as everyone does? Because i thought to represent equations 100% symbolically. It is not necessary, but then isn't that one of the strengths of Maple? AKS.

Using subliteral as the subscript is annoying in several ways: 1) For example if i set: i:=1 and then use the subliteral to create x with subscript i. I would expect Maple to display x with the subscript 1. However it still shows with the subscript i. Is there a way around this?

Thanks, i tried it out and it works. Not much of a shortcut though. Too many steps. Anyway thanks for all the replies!! :)

thnx for the clarification. New questions: 1) So far, i am using the subliteral either from the palette or with the following command: `#msub(mi("A",mathcolor = "#00a050"),mi("∗",mathcolor = "#c800c8"))` Is there a shortcut key for the subliteral command? 2) Also when i used subliterals, when i try to use the drop-down menu (right-click on a math expression) and use the solve >> isolate expression for command on a subliteral, i don't seem to get a result. Nothing happens. The manipulate equations works though. Thanks in advance.

you are right there. To really use subscripts in equations, the subliteral of the palette is to be used. Am i right?
