How is it possible to differentiate between the least and most important bits

Calculate arithmetic addition of the following decimal numbers using 8 bit 2's complement representation. -4410 + 2710 Complete the following value from (i) to (vi) with the correct answer. Representation using 1's complement Representation Addition arithmetic Range of 8 bit number (2's complement) Number using 2's complement (2's complement) 4410 (i) (i) (v) (vi) 27 10 (ii) (iv)

Show each of the following calculations in 4-bit two's complement notation. In each case, convert the result (in binary) back to a decimal number. (a) (b) (c) (d) - 5+7 - 3 +3 6-4 -2-3 Suppose we use six bits to represent a two's complement binary number. (a) (b) What is the largest number that can be represented?. What is the smallest number that can be represented? How many total base-10 numbers can be represented? ). Suppose we use six bits to represent a two's complement binary number. Perform the following additions, indicating when overflow occurs: (a) 010101 (b) 100000 001101 110011 100110 111111 (c) (d) 010101 101111

If you wanted to represent 19 different things, how many bits would you need? Why?
