Can anyone explain (or parse) how to get the answer to 10 across and 11 across.
X by itself at the end of matrix? Not right - not x according to subject (8)
Zero's appeared - one making call about that? (8)
I know the answers are Thematic and Croupier but why?

[dannyk13]

Croupier - o(zero)up(appeared) inside crier(one making call)

[scorpiojo]

Crier (one making a call) around 0 up (appeared)

I can see ..........the mat(r)i(x) but nothing for the c

[dannyk13]

Me too

x by itself = 100 - C

[PurpleJumper]

Got it! ten times ten = 100.. or x x x = c
