Answer:
The summands are 4 and 5. The sum is 9.
Step-by-step explanation:
In the binary system, the digits, starting at the right and moving to the left are:
1's
2's
4's
8's
etc.
100 = 0 units + 0 2's + 1 four = 0 + 0 + 4 = 4
101 = 1 unit + 0 2's + 1 4's = 1 + 0 + 4 = 5
In decimal, the addition is:
4 + 5 = 9
The summands are 4 and 5. The sum is 9.
