test class for addition of two numbers

Hi,
I have written the apex class for addition of two numbers. but for writing the test class i have issue.
Program is
--------------
public class Add 
{    
public integer a;
public integer b;
public integer c;
public integer addt()
{
    c=a+b; 
    system.debug('the result is'+c);
    return c;
}      
}

My test class
-----------------
@istest
public class Addtest
{
static testmethod void testadd()
{
    Add ad=new Add();
    integer res=ad.addt();
    system.assertEquals(res);
}
}
the test class is throwing error as
"Method does not exist or incorrect signature: void assertEquals(Integer) from the type System"

Any guidance please

Thanks in advance.

make these changes in order for your code to be more meaningful.

Class 
public class Add 
{    
    public integer a;
    public integer b;
    public integer c;
    public integer addt(integer a, integer b)
    {
        c=a+b; 
        system.debug('the result is'+c);
        return c;
    }      
}


Test Class 
@istest
public class Addtest
{
    static testmethod void testadd()
    {
        Add ad=new Add();
        integer res=ad.addt(2, 5);
        system.assertEquals(res, 7);
    }
}
