I didn't work much upon it but as per my little experience i think it is right if you could request a list by using Input L1 and omit the expr("{"+Str1) but the user will have to manually put in the bracket.
Also, a list variable is destroyed. Usually, destroying strings are favorable to destroying lists.

The speed and size work well. I think the string is a pretty good way of doing it.

You would still be destroying a list variable….

Copy it to a temp variable (like L2) and use that maybe?

Ooh nice, good job.

Would it be easier to input a list instead though?

Nice, although you could just do E+A^-1->E. Also, since C is no longer used, you do not need to do "DelVar C".

The input goes off of my screen, but that is easy to fix. Thank you.

Input "Enter resistor values, separated by commas", Str1 sum(expr("{"+Str1) ֿ¹) ֿ¹ Disp Ans,round(Ans,2

Input "Repeat (n) times:",N
Delvar E
For(B,1,N
Input "R:",A
A^-1
E+Ans->E
Delvar ADelvar C
End
Disp E^-1, round(E^-1,2)
"

About all I can see, it's pretty darn optimized! The last part is a stylistic choice, just removes the "Done" statement.

I wrote a program for the formula:

(1/Rt)=(1/R1)+(1/R2)+(1/Rn) //I don't have time to use subscripts right now

Here is my current code:

Input "Repeat (n) times:",N //input number of resistors in parallel 1->B //reset the loop variable Delvar E //clear the current answer For(B,1,N //repeat depending on how many resistors you have Input "R:",A //input the resistance in ohms of an individual resistor A^-1 -> C //I am using the inverse button here E+C->E //take the total and add the resistance Delvar ADelvar C //remove any source of error End //end the for loop Disp E^-1 //display the correct answer Disp round(E^-1,2) //display a rounded answer

How can I optimize this code?
