  1. ASM instruction - inc, dec, neg, mul, imul -

  2. inc, dec, neg기본형 • 1 operand => inc destination => dec destination => neg destination • inc , dec메모리도 ++, -- 가능 플레그는 불가능 • neg는 +,- 변경

  3. mul기본형 • 1 operand => mul source • EAX가 중점 => AL * BL = (1byte) (1byte) (2byte) => AX * BX = (2byte) (2byte) (4byte) => EAX * EAX = (4byte) (4byte) (8byte) AX AX DX EAX EAX

  4. imul기본형 • 1~3 operand => imul source => imulreg source => imulreg source imm • 양수끼리의 곱하기에서 사용

  5. Ex) Input 3은 뭘까? 키읔 Input 1 = 6 Input 2 = -3 ANSWER= 23 Input 3 = (?)
