I've been using LaTeX for my math homework and notes for about 6 months now. However, I'm really quite new to anything that uses the real power of TeX.
When I used to do my homework by hand, I always meticulously crossed my z's and 7's, like this:
and likewise for my z's.
Is there a way to make LaTeX automatically cross my 7's and z's (and capital Z's, for that matter) within math mode? I'd like to leave the 7's and z's as normal within body text. ALso, I would prefer not to use a new command; I want a crossed 7 whenever I type 7 as normal, and likewise for Z/z.
My first idea for a solution would be to use the "negative space" command somewhat like this:
However, I'm not sure this is the most elegant solution, and I still don't know how to make LaTeX do it automatically whenever I just type something like
$3+4 = 7.$
Thanks for any help anyone can offer!
