Answer / saurabh gupta
To add a number in macro use %EVAL macro
Example
%Let a= 2;
%Let b= 3;
%Let c= &a + &b ;
then it will give you value
c=2 + 3
but If you will use %eval it will give you sum
%Let c= %eval(&a + &b)
Now this will give you the correct answer
c=5

Answer / nani
%macro add(a,b);
%if (%datatyp(&a)=NUMERIC and %datatyp(&b)=NUMERIC) %then %
do;
%put The result is %sysevalf(&a+&b).;
%end;
%else %do;

You can invoke the ADD macro as:
