as promised.
also, this was a double update, so don't forget to read chapter cv (you'll know what number it is by the end of this hopefully)
i = 1
v = 5
x = 10
l = 50
c = 100
basic rules:
>a number cannot be repeated more than three times
examples:
iii ✔️
iiii ❌, iv ✔️
xxx ✔️
xxxx ❌, xl ✔️
lxxxx ❌, xc ✔️
>if a smaller number follows a bigger number, they add
examples:
i is less then v (1 is less than 5), so vi = 6 ✔️
v is less than x (5 is less than 10), so xv = 15 ✔️
x is less than l (10 is less than 50), so lxx = 70 ✔️
>if a smaller number come before a bigger number, they subtract
examples:
i is less then v (1 is less than 5), so iv = 4 ✔️
i is less than x (1 is less than 10), so ix = 9 ✔️
x is less than l (10 is less than 50), so xl = 40 ✔️
x is less than c (10 is less than 100), so xc = 90 ✔️
here's some demonstrations:
i = 1 ✔️
ii = 2 ✔️
iii = 3 ✔️
iv = 4 ✔️
v = 5 ✔️
vi = 6 ✔️
vii = 7 ✔️
viii = 8 ✔️
ix = 9 ✔️
x = 10 ✔️
some possible questions you may have:
>why is 8 viii, but 9 is ix? see the first rule
>that's great, but what happens after 10? great question! onward we go!
xi = 11 ✔️
xii = 12 ✔️
xiii = 13 ✔️
xiv = 14 ✔️
xv = 15 ✔️
xvi = 16 ✔️
xvii = 17 ✔️
xviii = 18 ✔️
xix = 19 ✔️
xx = 20 ✔️
some possible questions you may have:
>19 looks complicated! why? how?! the first x is larger than what follows, so think about adding that (+10). the next number is i (1) which is less than x (10), so 10 - 1 = 9. 10 + 9 = 19
>okay, i'm getting the hang of the one's place, but what about higher ten's place digits? onward!
x = 10 ✔️
xx = 20 ✔️
xxx = 30 ✔️
xl = 40 ✔️
l = 50 ✔️
lx = 60 ✔️
lxx = 70 ✔️
lxxx = 80 ✔️
xc = 90 ✔️
c = 100 ✔️
