### A good answer might be:

>                   1 11      1  1
>        0F4A → 0000 1111 0100 1010
>        420B → 0100 0010 0000 1011
>        ----    --------------------
>                0101 0001 0101 0101  → 0x5155

# Additional Addition Practice

The carry out of zero from the left column in the binary addition indicates that the sum can be contained in that number of bits

Sometimes a hex addition problem is easy enough to do without converting to binary:

>        014A
>        4203
>        ----
>        434D

It may be helpful to use your digits (fingers) in doing this: to add A+3 extend three fingers and count "A... B... C... D".

### QUESTION 9:

Compute the following sum using 8 bits. Is there overflow?

>        1101 0010
>        0110 1101
>        ---------
