=IMPRODUCT(2+i2,2-i2)
Excuse me, but I believe the terms +2*i2 and -2+i2 do in fact cancel

should be written:
(2+2i)(2-2i)
2*2 + 2*2i + -2*2i + (-4i^2)
=4          +         (-4)(-1)
=8

            =
2*2+2*i2-2*i2-i2*i2
            = 4 +i4
-i4 -(4)          [i2*i2=-4]
            = 8
But Calc lists the answer as 4.

       Are there any
complex functions that really work other than
IMREAL()? (It only reads the real part of a complex
number.

I confirm this result with 3.5.4.2, Ubuntu 12.04

Excuse me, but I believe the terms +2*i2 and -2+i2 do in
fact cancel 
each other out.
This leaves 2*2 and -(-4) as the remaining terms, or 4 + 4 =
8.

Or, have I missed something?
