Compute 11_2 + 110_2 + 100111_2 + 101011_2 + 111_2 + 1011_2 + 1100101_2. Give your answer as a base 2 integer.
112 = 3
1102 = 6
10001112 = 71
1010112 = 43
1112 = 7
101112 = 23
11001012 = 101
3 + 6 + 71 + 43 + 7 + 23 + 101 = 254
Convert back to base 2
254 / 2 = 127 R 0
127 / 2 = 93 R 1
63 / 2 = 31 R 1
31 / 2 = 15 R 1
15 / 2 = 7 R 1
7 / 2 = 3 R 1
3 / 2 = 1 R 1
1 / 2 = 0 R 1
