Explanation Given Information: The provided hexadecimal numbers are 7 − 1 B . Formula used: Procedure to subtract the hexadecimal number: Find the first number in the left vertical column, find the second number in the top horizontal row, and find their sum at the intersection in the table. According to the hexadecimal form to decimal form conversion method find the place value of each digit in the given hexadecimal number and multiply by its corresponding power of 16 . The complementary pair of the hexadecimal is always consisting in positive and negative, if the digit is positive the complementary of that digit will be negative. The complementary pair of some of the digits are, Complementary of 0 is F, 1 is E, 2 is D, 3 is C, 4 is B, 5 is A, 6 is 9, 7 is 8 . Calculation: Consider the provided hexadecimal numbers 7 − 1 B . For the addition and subtraction of hexadecimal numbers refer the table 16.3 . These numbers can be written as, 7 − 1 B Take the compliment of each digit in the number to be subtracted, B → 4 1 → E Now, add both hexadecimal numbers, 7 E4 Now, use the table for the addition of 7 + 4 which is found to be B , and the addition of 0 + E is E . Thus, 7 E4 EB As, the number to be subtracted is larger so the answer will be negative, thus taking the compliment of each digit in result, E → 1 B → 4 Thus, the result of the addition is − 14
