Unlike your other posting, this is an InDesign question. You need to learn how to set the units for your document. To do so, make your ruler visible (View > Show Ruler). Right-click or Control-click on the ruler and choose your preferred units—inches, picas, millimeters, etc.
To set a default for a future document, set the options when no document is open. Preferences > Units and Increments.
I'd assume that an instructor would have covered this in class, or provided this information is assigned readings.
no the college I go to took instructing us on adobe away. they tell us use Lynda.com. its hard to find specific videos to help me with these assignments. I'm trying to find videos on how to do process books and posters.
Say he sets the width to 6 inches, and height 8.25 inches I type that in and it goes to 6p0 width and 8p3 height. Also, he sets margins to 0.375 inches and clicks make all the same, mine becomes 2p3. I really don't know whats going on. PLEASE help.
To address this specific question—InDesign defaults to measuring in picas and points. When you type in a number like "6", you are assuming inches but InDesign is assuming picas and displays the number 6 as 6p0 (6 picas, 0 points).
As per Steve's response: close all the open documents. Go to InDesign > Preferences > Units and Increments (on Windows it is Edit > Preferences > Units and Increments) and change the default to inches.
Pick OK, and make a new document. From now on, InDesign will default to inches.
