Step 2—Now R's-1 complement the remaining digits:
Now let's R's complement the same number using both methods:
Now let's do some subtracting by using the R's complement method. We will go through the
subtraction of 310 from 910 (00112from 10012):
Step 1¾Leave the minuend alone:
10012 remains 10012
Step 2—Using either method, R's complement the subtrahend:
11012 R's complement of subtrahend
Step 3¾Add the R's complement found in step 2 to the minuend of the original problem:
