Please help with the following in regards to Nand2Tetris, and hack code, so hack assembly and hack vm. There can be more that one answer to a question if so please explain why. 1d. A symbol may be: a. @followed by a number b. @followed by a lower case word c. @followed by upper case word d. a and b e. b and c 1e. Every boolean expression of N inputs and one output can be implemented a. using a combination of D flip-flops, multiplexors and registers. b. by connecting the output directly to all of the N inputs. c. using a combination of And and Or gates. d. using a combination of And, Or and Nand gates 1f. In twos-complement arithmetic, to create a negative value of a number X: To subtract X from Y: a. invert (Not) every bit in the number X. b. invert the most significant bit of X. c. add 1 to X, and invert every bit. d. subtract 1 from X, and invert every bit e. add 1 to X f. invert every bit of X and add 1
