# Math Help - Subscripts

1. ## Subscripts

In my most recent post to Linear and Abstract Algebra I had a lot of trouble with subscripts

$N_1$ was OK, but for some reason putting N_k or N_{k} in between $and$ did not work

I also wanted N to be subscipted by j-1 and j+1 but N_{j-1} and N_{j+1} did not work

Can anyone help?

Use these tags $$...$$
$$N_{j-1}$$ gives $N_{j-1}$
