Duplicity means deceitful so kinda like double-sided or a liar <span />
Both are a number (6) multiplied by a variable (z).
However, 6z is the correct way to write this.
We usually write the number first, that's just the way it's done.
It sort of makes sense because 6z is literally equal to 6 z's.
Because his wife is beautiful, young, and wealthy. Hope this helps <3
