don't know c so i can't give you code but i can do it logically:





create two random numbers 0 - 10;


then biggerNumber (randomly choose add or subtract) smallerNumber





the answer will never be more than 20 and it can never be negative cause no matter what, your subtracting a smaller from a bigger (or the same value which is 0)
Reply:int a;


int b;





b = rnd() % 10;


a = b + rnd() % 10;





printf("%d - %d = %d\r\n", a, b, a-b);
