Using the Math
Instructions
Most math instructions use three parameters, Source A, Source B, and
Destination (additional parameters are described where applicable, later
in this chapter). The mathematical operation is performed using both
Source values. The result is stored in the Destination.
When using math instructions, observe the following:
