Calculations 5, 6 and 7

[Leah K.]

Hi guys:

Hope you had a nice long weekend. I was reviewing Module 5 over the
weekend, and tried to find where in the module or in the book there
are descriptions of Calculations 5, 6 and 7 - I see them being
introduced in Module 4 I think, and then I see them being done ine the
examples - but s there a place where they are explained - what
included in them, etc in more detail.
I am sure I am missing something. Please help!

Thanks,

Leah.
