### A good answer might be:

- Both

# Binary Addition Algorithm

The Binary Addition Algorithm works for both methods of integer representation. The same MIPS instruction (`addu`) is used for both. However, the overflow condition is different for each representation.

Binary Addition Algorithm: detecting overflow
Unsigned Binary | Two's Complement
--- | ---
The result is correct if the carry out of the high order column is zero. | The result is correct if the carry into the high order column is the same as the carry out of the high order column. The carry bits can both be zero or both be one.

### QUESTION 3:

Use the Binary Addition Algorithm on these 8-bit patterns:

    1010 1011
    0101 0101
    ---------
| Does overflow happen for: Unsigned Binary? Two's Complement?
