Discussion Forum—A Way with Words, a fun radio show and podcast about language

Your initiarithmetic puzzle brought me back to Middle School. I remember playing this in class one day for fun. Some of the ones I remember were;

18 H on a G C
9 P in the S S (although this has now changed ^_^)
88 K on a P
7 G W of the A W
26 L in the A
7 C in a R

I'm sure there were more, but these are the only ones I remember. Great fun, thanks.
