10 + 100 ≈ 2 + 4 = 6
101 + 111 ≈ 5 + 7 = 12
10110 + 1010 ≈ 22 + 10 = 32
Using the following table as a reference for the values. (Off my portable hard drive, have a huge text pad file where I tried to explain binary to a classmate)
128 64 32 16 8 4 2 1
0 0 0 0 0 0 0 0
EDIT: Not entirely sure if ≈ is the right symbol. Using it as "is the same as", not "is equal to".
