It looks like you're mixing up NSNumber objects (which cannot have
arithmetic operations done on them the way you're trying to do them)
with simple int variables.
But before I try to answer your question fully: can you send the rest
of the code for this method, including variable declarations, so we can
be sure of exactly what's going on?
FYI: if a C array (or anything else from C) seems better for your
purpose, there's no problem using them in Objective-C. It's a strict
superset of C.

Hi Im new to all this and have had a few successes in making my
programming do what I want it to do. Yet I am struggling with some of
the basic stuff. ANSI C for example I can add two integers together
quite simply. However in OBjC when I recall two integers from an array
and assign them to a variable I keep getting the following warning
message: assignment makes pointer from integer without a cast. What
does it mean? How do I make it right? Please forgive my dimness I'm
quite new to all this.
inputArray = [[NSMutableArray alloc] initWithCapacity:7];
x = [[sender selectedCell] tag];
[inputArray insertObject:[NSNumber numberWithInt:x] atIndex:0];
num1 = [inputArray objectAtIndex:0];
num2 = [inputArray objectAtIndex:1];
answer = num1 + num2;
