Line 24:

* +7 is written 0 0111

* −7 is written 1 1000

and their sum is written as "1  1111" (one of two representations of zero in this system; zero can also be written as "0  0000").

On modern machines, in classic binary notation, −7 would be written 1  1001, and the sum of −7 and 7 would give "0  0000"; this "two's complement" system thus needs only a single representation for the number zero.
