	correct = random1 + random2;

	if (answer == correct)
	{
		cout << "Good Job, you got it right.";
	}
	else
	{
		cout << "OH NO, you got it wrong." << endl;
		cout << "The correct answer is: " << correct << endl;
	}
	return 0;
}

Everything is right, except the random numbers keep coming up as the same number, i cant get them to actually be random.

Yes, and thats because of this statement: srand(time_t(NULL));
Making it: srand(time(NULL)); must randomize it for you.

and: http://www.cplusplus.com/reference/clibrary/cstdlib/rand/

Hope it HELPS!!!

Instead of

srand(time_t(NULL));

use

srand( time( NULL ) );

But if i change it to that this warning shows up.

1>c:\users\grimm\documents\visual studio 2012\projects\mathtutor\mathtutor\mathtutor.cpp(11): warning C4244: 'argument' : conversion from 'time_t' to 'unsigned int', possible loss of data

Nevermind, fixed the warning, all i had to do was make it srand((unsigned int) time(NULL));. Thanks for you help guys.
