Thank you Neil and Scott for your responses.
You would think they would pay somebody to check the work of the printers before sending this out to customers!! At least I hope it was the printer's mistake. It is lucky that it was done wrong enough so that it gave me some doubts. If anybody from CSA is reading this, take note. We don't have time to verify every equation presented to us in codes.

The ACI Eq. 9-7 is written thus:

       Mcr                   Mcr
Ie = [-----]^3 * Ig + [1 - [-----]^3] * Icr
       Ma                    Ma

This should also be presented in courier font.
