Hi, I'm wondering if it's possible to write a sum like this in Wolfram Alpha:
$\sum \limits _{i = 1}^{3} a_i $
I'd like to get the result $a_1 + a_2 + a_3$ in WA.
Thank you for your time.
This
Sum a(i),i=1 to 3
returns
a(1)+a(2)+a(3)
and, if you really must, you can try clicking on the Math Input button in WA to see if you can get it to correctly interpret and display subscripted variables
Hello @Bill Nelson, thank you very much for your precious help.
