+For example, the word "cabbage" is worth 14 points:
 
 - 3 points for C
-- 1 point for A, twice
-- 3 points for B, twice
+- 1 point for A
+- 3 points for B
+- 3 points for B
+- 1 point for A
 - 2 points for G
 - 1 point for E
-
-And to total:
-
-- `3 + 2*1 + 2*3 + 2 + 1`
-- = `3 + 2 + 6 + 3`
-- = `5 + 9`
-- = 14
