Hello my dear please I need the solution fast if you can :-)

Complements, Arithmetic Operations, & Codes Q.1. Subtract the following numbers without using complement. ( 14 points) A. (1 0001 0100 1001)2 (0 0000 1010 1001)2 B. (1111 0100 10102 - (0100 1001 0101)2 C. (+45) - (-30) D. (-23)16 - (-32)16 E. (+45) - (368 F. (+10)8 -( 28 ( 1 6 points) Q.2. Add the following numbers and display the answer in binary form. A. 3897 (BCD) + 4678 (BCD) B. 8977 (BCD) +9765 (BCD) Q.3. Perform the following subtractions by using the 2's complement. C 12 points) A. (35)10 - (25)10 B. - (66)10 - (44)10 C. (-85)10 + (-34)10 D. (+18)10 + (-71)10 C. (110101)2 (111)2 (assume we are using a 2's complement, 8 bit system) D. (110101)2-(111)2 (assume we are using a 2's complement, 8 bit system) E. Convert (110101)2 to base 10 if we are using a 2's complement 8 bit system. Hint: use 2's complement of the negative number to find the positive number this represents. Alternatively, consider the MSB as the "-32" position and add the other bits accordingly. F. (110101)2 (111)2 (assume we are using a 2's complement, 8 bit system)
