### A good answer might be:

- Reflect the bits in $8:

       nor  $8,$8,$0

- Add one to $8:

      ori  $9,$0,1
      addu $8,$8,$9

# Example Program

Here is a program that does that. There are much better ways to load a register with a negative integer. However, this is a nice example of bit manipulation.

    ## handMadeNeg.asm
    ##
    ## Program to demonstrate two's complement negative
    ##
    ## The program adds +146 to -82, leaving the result in $10

            .text
            .globl  main

    main:
            ori      $7, $0, 146        # put +146 into $7
            ori      $8, $0,  82        # put 82 into $8
            nor      $8, $8,  $0        # reflect
            ori      $9, $0,   1        #
            addu     $8, $8,  $9        # add 1: $8 = -82
            addu    $10, $7,  $8        # (+146) + (-82)
