the arm subtraction instructions carry ( sbc , rsc ) interpret carry flag (c) as: 0 means borrow 1 means no borrow why carry flag c inversed make arithmetic? sbc r0, r1, r2 @ r0 = r1 - r2 - !c we know grade school that a = b - c = b + (-c) and elementary programming classes negate number in twos complement invert number , add 1 a = b + (~c) + 1 and works out because when feed adder logic our values invert second operand , invert carry in.
