First 3 powers of 2:
2^0 = 1
2^1 = 2
2^2 = 4
so 101 would be 1 x (2^2) + 0 x (2^1) x 1 x (2^0) = 1 x (4) + 0 x (2) + 1 x (1) = 4 + 0 + 1 = 5
and 111 would be 1 x (2^2) + 1 x (2^1) x 1 x (2^0) = 1 x (4) + 1 x (2) + 1 x (1) = 4 + 2 + 1 = 7
But you could have just counted it :).
000 = 0
001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
