 Scales
 ================================
 
-With large numbers, values are separated in groups of three. The separator is `do`.
+With large numbers, over four digits, the typical convention is to write them out with a space or letter between each group of three.
 
-	wa padorechiko
+	we parechi moku
-	wa pa do rechiko
+	[numeral] 123 45
-	[numeral] 1 [thousands] 234
-	1,234
 
-If the entire group is zero, then the number itself can be skipped.
+To simplify numbers, `do` is used to indicate three zeros.
 
-	wa padorechiko
+	padochi
-	wa pa dodo rechiko
+	1 000 2
-	[numeral] 1 [thousands] [thousands] 234
+	10,002
-	1,000,234
 
-Scales are based on the previous number, not the total magnitude. In English, one would say "1 billion, 1 thousand." In Miwāfu, one would say "1 thousand 1 thousand".
+In addition to `do`, there are additional scale syllables used for large numbers.

-In addition to using the thousands skip, there are additional amounts that can be interspersed with the number or used at the end.
+Like `do`, these can easily be combined together to indicate more zeros.
