Timelapse - Egyptian World - Crystal Room

Can someone please explain to me in a simple way about solving this puzzle.

Now I have the table of the God and the Animal, but what does it mean the Inital Value, Numeric Adjustment, Adjusted Value. Let me show you what I mean which I got from Timelapse Review and Walkthrough.

God Animal Inital Value Numeric Adj Adj Value
Knumim Goat 5 +4 9

I don't understand this.

Can someone help me.

Thank you.

In the Crystal Room you must do this on each crystal - select the god's (animal) icon, in the same relative position they are on the columns outside. Select the symbol (staff, water, etc.) that goes with each god. Select the correct number on each crystal, according to the formula. Observe the number on the column outside, then add or subtract, following the instructions on the parcment you found. This also assumes you have learned to read the numbers from the other parchment (the one showing knives, baskets, etc.) Notice also the colors.
