Do you cross your sevens?

A seven is supposed to look like this: 7 not like this: 7. What's up with all these people who habitually, without any thought whatsoever, draw random lines through their sevens which don't make them look like a seven any more!?

No because it's not a 7 if it's crossed

That's an ex-seven.

Works for me

Nein.

No, but on a mildly related note, I recently started crossing my Zs.

Occasionally. I also do those angular 3's sometimes, when I'm feeling fancy. p,o

Habitually.

My third grade teacher made us cross our 7's and Z's, but I have not done so since.

Usually I don't, but if my 7 looks too much like a 1, then I put a cross through it. That's only occasionally though, and I don't do it out of habit.

Yes. I also cross my z's. Never used to do either until I started doing lots of chicken scratch and had to be able to tell a 7 from a 1 and a z from a 2.

Characters should only be crossed to disambiguate them. Nothing else in the English alphabet or Arabic numerals is similar enough to a '7' to warrant this.

I try to be consistent in crossing my zeroes, but I frequently forget to.

Doesn't a zero with a line through it mean "no solution" in algebra, though?

It doesn't happen often beyond algebra that that symbol sees meaningful use. In upper-division math, you only need to express a "no solution" as part of a proof, in which case it's more appropriate to write out "no solution".
There's always "DNE", to boot.

Actually, it means "empty set". The perpetuation of the idea that it means "no solution" rests on the shoulders of a million misinformed high school algebra teachers.

I've considered dotting my zeroes, which would ease all the confusion.

Because it's more convenient to the next number. Yes.

I've always used the Greek phi (i.e. Φ) to represent an empty set. The slash on the phi is vertical, whereas I slash my zeroes diagonally.
Dotting zeroes is not a bad idea, though. I might try switching to that.
