The numeral "7" - With crossbar or without?

Flat-top 3, open 4, serifed & crossed 7, crossed Z

crossed 7’s and z’s, closed 4’s (though my 4 is angeled like a / and my 9 more like a ) no cross on zeros. Grew up in california, though my dad’s a scientist and apparently the crossed 7 is the norm so they don’t confuse it with a 1. Most people i know don’t cross their 7’s or z’s though (my dad doesn’t even cross his z, I dunno where I picked that up)

the first time I wrote a 7 on the board my kids (japanese students) freaked out, it was pretty amusing.

Crossed sevens, sometimes crossed zeds if I remember, open fours (I did not know that anyone wrote them closed), no cross on zeroes.

I cross my 7s and my zeds, but I distinctly remember making a conscious effort to start doing so in the fourth grade. Now it’s so second-nature that even writing at top speed I cross both.

Cross 7s, cross zeds if I’m printing, closed 4s.

I was taught to make a slanted 7, so no need to cross. 1 is a straight vertical, so it doesn’t get confused. Open top 4, and put the bar on the 5 last.

Actually, I still make all my numbers the way I learned them in first grade. They’re legible enough that it’s never been a problem.

No cross on 7 or Z, open 4, and the only time I crossed a zero was when I needed to distinguish it from the o in an NES password. Long passwords are one thing I’m glad the gaming industry no longer has a need for.

Regular 7s

Open 4s

No crossing of the 0’s

Fuck I hate that, the Italians do that too. I’m forever making mistakes with hand-drawn German and Italian schematics because I can’t distinguish the 1s and 7s.

Regular 7s. Open 4s.

Interestingly, my lower case gs and my 8s are indistinguishable, if not for their position. Also, I had to start putting tails on my ts and is after intro to electrical engineering.

Crossed sevens, open fours. Crossed zeros since my first year doing hedge fund audits when I had people writing cusips on post-its for me and got horribly frustrated for anything that had both a 0 and a O.

Cross nothing, open 4s. People who do it differently are just being silly.

Crossed 7s and zs

Open 4s

I find this helpful when I write in my lab book. Otherwise I’d mix my 4s and 9s, 7s and 1s, and zs and 2s (my handwriting isn’t great.)

If I need to mix a lot of 0s and Os I’ll cross the 0. I don’t typically do this though.

I still ought to my clearly differentiate my 5s and Ss. The way I write them they tend to look similar.

Crossed Ts and Zs here. I got in the habit way back in German class.

I’m a very simple person. Plain 1, 7, 0 and Z. Open 4.

Crossed 7s and Zs. I was not taught this way - I remember first seeing it when I was in the third grade or so when my teacher did it, and I thought it looked cool. A few years ago I started doing it for no apparent reason.

I don’t cross my zeros, but I feel as though I should. That’s a hard habit for me to get into - I think I’ve tried.

4s are open, but when I’m writing with the big scrawls and loops and it’s just for my own notes anyway, the two sides on top almost form a point.

Do not put a cross bar on 7, a 7 with a cross bar could mistaken for a Z. The cross bar should go on a Z in a math problem, this keeps it from being confused with a 7. This is the way I was taught in advanced math classes 40+ years ago.

7 - with a crossbar
1 - with an upstroke
Z - cursive with crossbar, print without

They do that here, too. I used to write them that way myself, but when I was working in NY people kept mistaking them for 7s, so now I write them American-style.

I still cross my 7s.

That’s the way I was taught to write my numbers, too. Still do.
