I used to use the slash on 7s when I was in Jr high because it was legit and nobody did it.
But, like... Why? What purpose does it serve? It's not like the slash through a 0 to differentiate it from an O.
My 7s and 1s look too similar without it, to the point it was affecting my math grades. This was sixth grade. I've done it ever since
We always were forced to use the foot on the 1 so I never even thought of that. 😮
🎵 You used the serif! but you didn't use no deputy!
I'm now calling the line through my 7s the deputy
I wholeheartedly endorse this course of action 😁
In my country the slashed 7 became mandatory in the national curriculum in the 1930's. Our military strongly requested this in order to achieve better accuracy in artillery fire control - in those days every calculation was done by hand and mixing 1's and 7's could easily have deadly results.
This practice was quickly adopted by the whole population and it was a great success with no drawbacks. The slashed 7 makes it impossible to mix 1's and 7's, therefore it is the superior choice.
