Expert Solution
Step 1
2’s complement notation:
2’s complement notation is a method of representing negative numbers in binary form. It is the most common way to represent signed numbers in binary. It works by taking the number in binary form and inverting each bit (switching 0s to 1s and 1s to 0s) and then adding 1 to the result. The leftmost bit is used to indicate whether the number is positive or negative.
