[Solved] Help with subscripts

[reddogg]

I want a right subscript to be : t-1 but when I enter the minus sign the formula shifts up to the regular level. I can get t-1 as a right subscript only by enclosing it in parenthesis : (t-1). But that's not what I want. Any suggestions?

Thanks,

The minus sign is a "binary operator" and needs something before and after it to work. Try this code:

Code: Select all

t_{{}-1}

Parentheses show up on the page, but braces do not. Using braces makes any characteristic apply to a group of stuff. So to get "X sub t-1", type
X_{t-1}

The enclosing braces instead of parenthesis do the trick! Thanks for the help!
