Does anyone have this book? I've just done page 13 with my son. (Practice type 16). The last question on the page is:

XD is to CW as UG is to ( ).
We make it ZZ but according to the answers in the back of the book it should be FT. How do you get FT? Or is it a mistake in the book?

I remember this one being horrid. Its a sort of -1 with a switch around.

Subtracting one letter from X = W
Subtracting one letter from D = C

Swap them around to get CW

Likewise Subtracting one letter from U = T
Subtracting one letter from G = F

Swap them around to get FT

Oh, I didn't realise you could swap them around.

It is a mirror code.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

XD is to CW as UG is to ( ).

X is a mirror of C
D is a mirror of W

Mirror of U is F
Mirror of G is T
