You will probably want to use a string. Do you just want to display it, or return the string? The number to string is often referred to, but I find it to be too slow, especially when you only want to convert an integer. I typically use some variant of this:

;N is the number (non-negative integer) DelVar A".→Str1 Repeat not(int(B N10^(A→B sub("0123456789",1+int(10fPart(Ans)),1)+Str1→Str1 A-1→A End sub(Str1,1,length(Str1)-1→Str1

I think that will work, but I didn't test it. Then you can do your fun math by storing it as a string :)

so just today, we learned about binomial expansion and man do i want to make a program for it. anyway, i have the basic setup, (exponent nCr term number - 1)((coefficient)^exponent-term)((coefficient)^term) but i want to also show the variables like x^2y^3 or something like that with the coefficient. can yall help, thanks
