This is a very simple one. I try to add 2 macro variables, which are initialized from SAS EG prompts (Number1 and Number2). I currently use this code it should work for non integer number):
%let Result = %sysevalf(&Number1.,integer) + %sysevalf(&Number2.,integer); %put &Result.;
Unfortunately, only the expression rather than the result is printed.

Your problem is independant of Eg prompts.
When a macrovariable is created as follows :
%let mv1=1; %let mv2=2;
The compiler only performs text substitution so you wil end up with &mv.=1+2.
If you want to evaluate the resulting expression you have to enclose the whole
expression in an evaluation function %eval() or %sysevalf
%let mv=%eval(&mv1.+&mv2.); /* => 3 */
