Question
Please write all the process.
1.. Perform the following multiplications. Assume that all values are unsigned numbers. (No problem with unsigned (always positive) numbers, just use the same standard techniques as in base 10.)
a.1010 * 0110
2.Perform the following multiplications. Assume that all values are signed 2’s complement numbers.
c.11101 * 11101
Expert Solution
Step 1
Given:
- Two numbers to be multiplied are provided in binary form.
- For problem 2, the numbers are in 2's complement form.
Task:
- For problem 1, perform the multiplication of the given two unsigned binary numbers using the standard multiplication technique. Show all the intermediate steps and the final result in binary form.
- For problem 2, perform the multiplication of the given two signed binary numbers in 2's complement form using the standard multiplication technique. Show all the intermediate steps and the final result in binary form. Also, convert the binary result back to the decimal representation of a signed 2's complement number.

Follow-up Question
2c. 11101 * 11101 is incorrect because the professor told me: In 2’s complement you must sign extend. I have to do it again. Please you can give the correct answer
