9's complement Method: Computers use those?

Migrated from logicaletter.com computers are intricate to understand at the superficial level, but at its core all you will see are logic. Logic makes everything. The invention of transistors allowed us to create logic gates and those logic gates allow computers to add. couple of XOR gates and AND gates can create a full adder. but how do computers subtract? they use something called 1’s complement because computer developers thought “screw this , we are not going to build another circuit for subtraction, rather we will use same circuit board that we use for addition”....
