Hi Guys!

This problem is relatively easy, but I can't help but think I am doing something wrong. Basically, I am checking some binary work by adding Hex numbers. The numbers are
4F1A5 and BD50. I used a calculator to find the answer to be 50A7A,but when I do it manually, I get 5AA7AA, which is wrong. Could anyone tell me what I am doing wrong?

This is what I did:

4F1A5 => 4 15 1 10 5
BD50 => 0 11 8 13 5

4 15 1 10 5
+ 0 11 8 13 5
---------------------
4 26 9 23 10
---------------
5 10 10 7 10 < -- There are carries in here, but I don't know how to show it on the computer
----------------------
5 A A 7 A < -- My Answer

* It looks clearer in the picture.

units digit: 5 + 0 = 5
tens digit: A + 5 = F
hundreds digit: 1 + D = E
thousands digit: F + B = 1A, so keep the A and carry the 1
ten-thousands digit: 4 + 1 (carried from the thousands digit) = 5

Sorry, the second number isn't BD50 it's B8D5.

Which is it? And in any event BD50 = (11)(13)(5)(0).

To Topspark:
The second number is B8D5 not BD50, that was a mistake on my part. The numbers associated with it are correct ( i think ) as it correlates to the hex equivalent of that digit (e.g B = 11, 8 = 8, D = 13, etc)

To Plato,

Thanks for the wolfgram. Apparently one of the binary numbers were wrong.

Thanks for the replies!

4F1A5 + B8D5

Units digit: 5 + 5 = A
Tens digit: A + D = 17, so keep the 7 and carry the 1
Hundreds digit: 1 + 8 + 1 (carried from the tens digit) = A
Thousands digit: F + B = 1A, so keep the A and carry the 1
Ten-thousands digit: 4 + 1 (carried from thousands digit) = 5

So 4F1A5 + B8D5 = 5AA7A.

use the build in calculator with your windows...
just set it to HEX...as simple as such...
