Criteria Alternatives Matrix

At the risk of sounding completely nerdy, the equations in table 1.3 of the Munger book (pg.13) are wrong. They are full of typos. Just encase some of you wanted to learn how to use the matrix, I thought I should let you know.

For example: The build more prisons equation reads,
-.25x105+.25x3+.25x0-.25x4=-26.5
The equation should read, -.25x105+.25x3+.25x0+(-.25)x4=-26.5

All of the equations in the table are wrong, many of them are much worse than the example shown here. You should follow example above for the correct formula.
