Different number systems
There are different number systems (or “bases”). We count in Decimal (or Denary) – base 10
MAC addresses in networking are represented in Hexadecimal – base 16
The digits in the problem have something in common. They are all 1’s or 0’s. Just 2 values. The number system that uses base 2 is called Binary

Representing a number in binary

2~7	2~6	2~5	2~4	2~3	2~2	2~1	2 ~0
128	64	32	16	8	4	2	1
1	0	1	0	0	0	0	0

128 + 32 = 160

160 is the same as 10100000

Addition rules in binary

0 + 0 = 0
1 + 0 = 1
0 + 1 = 1
1 + 1 = 10  (0 and carry the 1)
