## Binary to Denary

Going from base 2 to base 10 is as simple as multiplying the digits. For example the number 110010102 is calculated (using our base 2 table) as

(1 x 2^{7}) + (1 x 2^{6}) + (0 X 2^{5}) + (0 X 2^{4}) + (1 x 2^{3}) + (0 x 2^{2}) + (1 x 2^{1}) + ( 0 x 2^{0})

= 128 + 64 + 0 + 0 + 8 + 0 + 2 + 0

= 202_{10}

If the last bit (binary digit) is 0 then it is an even number.

If the last bit is a 1 then it is an odd number.
