In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
Binary numbers
12 ====> binary
Step 02:
binary code
0000 = 0
0 + 0 + 0 + 0 = 0
0001 = 1
0 + 0 + 0 + 2 ^ 0 = 1
0 + 0 + 0 + 1 = 1
0010 = 2
0 + 0 + 2^1 + 0 = 2
0 + 0 + 2 + 0 = 2
0011 = 3
0 + 0 + 2^1 + 2^0 = 3
0 + 0 + 2 + 1 = 3
This would be the sequence of operation to find each number
1100 = 12
2^3 + 2^2 + 0 + 0 = 12
8 + 4 + 0 + 0 = 12
The answer is:
1100 = 12
