Defining math functions

documentclass[aspectratio=1610]{beamer} 
usepackage{amsmath}

begin{document}
deffunction(#1){ 96* (#1)-16 *(#1)^2 }

%1. I am trying to condense the following two lines

pgfmathparse{3+function(1)}
letzpgfmathresult
z result is z %


%2. I would like store the result of the previous line in a 'variable'

%The following doesn't work

defmyfp(#1,#2){pgfmathparse{#1} let#2pgfmathresult}
myfp(3+ function(1),z)

% /This yields the right answer BUT z Result is z ..... Yields error



%3. Why does the following mess up%

letz7pgfmathresult

z7 result is {z7}

%4. PLEASE point me to relevant documentation!

          I am not sure I understand the question. However, if you want to call a macro z7 this does not work because macro names cannot contain numbers. And I had to remove a backslash to arrive at
