  \begin{itemize}
-   \item Normally in FMAC the top 64-bits is thrown away.
+   \item Normally in MAC the top 64-bits is thrown away.
    \item What if we stored those 64-bits in a 2nd register?\\
                (64-bit carry-out)
-   \item And what if the next FMAC added that "digit" on?\\
+   \item And what if the next MAC added that "digit" on?\\
                (64-bit carry-in)
    \item Again: a chain of these performs Vector-by-Scalar Multiply
   \end{itemize}
