Hi, we are a very experienced tutoring agency (a family business
actually) specializing in math. We have honed in on specific problems
that come up over and over again for students of all ages when it comes

to the sticky and hairy world of math. If you are a member of a
schoolboard, a state education department, or a teacher or
administrator of a school, you might be interested in a range of
booklets that we are making up, each one focusing on a basic operation
in math. We will happily send you a copy of any booklet you might be
interested in, and, if you think it is easy to follow and may benefit
your students, we would be happy to send you copying rights for your
school (a licence to copy would probably run at around fifty dollars,
although if you can persuade your schoolboard or state education dept
to buy this, of course you could defray the cost completely. Naturally,

a wider-ranging licence-to-copy, of this latter nature, would be rather

more expensive.)Anyway, by all means contact me at
mathhelpbooklets@mail.com Thanks for your reading time! 
Yours, 
D
