URGENT!!!!!

I HAVE THE ANSWER KEY attached but can someone please explain to me step-by-step how this works.

For example, when is the memory address referred vs just the address or when a number is added, how it is added and to what?

ra Assume the following values are stored at the indicated memory addresses and registers Address Value OxFF OxAB 0x13 0x11 0x100 0x108 0x110 0x118 Register Value 0x100 0x1 0x3 rax rcx %rda Fill in the following table showing the effects of the following instructions, in terms of both the register or memory location that will be updated and the resulting value Instruction Destination Value subg %rdx, 8 ( %rax) inulq $16, (Arax , %rdz, 8) incq 16(%rax) decq %rcx subq %rax, %rax Solution to Problem 3.8 (page 194) This problem gives you a chance to test your understanding of operands and the arithmetic instructions. The instruction'sequence is designed so that the result'of each instruction does not affect the behavior of subsequent ones.
