Solution 1

Maybe you can just double check your calculations with this?

Solution 2

You should review the binary operators "and", "or", "xor", and "not". Once you figure out what operator applies to the first two answers, it's easy to figure out what the answer to the third problem is.

You are to convert the hex to binary

  #AA0099   1010 1010 0000 0000 1001 1001
? #009966   0000 0000 1001 1001 0110 0110
  =======   =============================
= #AA99FF   1010 1010 1001 1001 1111 1111

and figure out which operation is used. In this example, or can fit, + too ...
Do the same with second example.

To me it looks like simple math. I think that your second result is wrong.

Here it is in C# as no language was mentioned:

C#

var col1 = new[] { 0xAA0099, 0x339900, 0x006699 }; var col2 = new[] { 0x009966, 0x990066, 0xEF4321 }; for (int i = 0; i < col1.Length; i++) { Console.WriteLine($"{col1[i].ToString("X6")} + {col2[i].ToString("X6")} = {(col1[i] + col2[i]).ToString("X6")}"); }

Which outputs:

AA0099 + 009966 = AA99FF 339900 + 990066 = CC9966 006699 + EF4321 = EFA9BA

After talking with ppolymorphe, you could do the following bitwise:

C#

int[] col1 = new int[] { 0xAA0099, 0x339900, 0x006699 };
int[] col2 = new int[] { 0x009966, 0x990066, 0xEF4321 };

uint mask = (1 << 16) - 1;

for (int i = 0; i < col1.Length; i++)
{
    var answer = (col1[i] | col2[i]) & mask | 0xaa0000;
    Console.WriteLine($"{col1[i].ToString("X6")} ? {col2[i].ToString("X6")} = {answer.ToString("X6")}");
}

Which outputs:

AA0099 ? 009966 = AA99FF
339900 ? 990066 = AA9966
006699 ? EF4321 = AA67B9
