- To subtract numbers in base 16, we start from the right side, just like normal subtraction. In this example, we subtract 4F base 16 from A3 base 16. We begin with the rightmost digit. Since 3 is smaller than F, we cannot subtract directly, so we borrow from the digit on the left. Borrowing in base 16 means adding 16 to the current digit. After borrowing, the 3 becomes 19, and 19 minus 15 equals 4, so we write 4. The digit A, which has a value of 10, becomes 9 after borrowing. Then we subtract 9 minus 4, which equals 5. Therefore, the final answer is 54 base 16.

- To perform subtraction in base 8, we subtract from right to left and borrow when needed. Let us use the example 52 base 8 minus 37 base 8. First, we start with the rightmost digit. Since two is smaller than seven, we borrow from the digit on the left. Borrowing in base 8 means borrowing a value of eight. After borrowing, two becomes ten in value, and ten minus seven equals three. The left digit is reduced from five to four. Next, we subtract four minus three, which equals one. Therefore, the final answer is 13 base 8.

- In conclusion, subtraction in different number systems is an important concept in arithmetic and logic operations within computer organization and architecture. Although base 2, base 8, and base 16 use different digits and symbols, the subtraction process follows the same fundamental logic. We always subtract from right to left, and when the top digit is smaller than the bottom digit, we borrow according to the base of the number system. In base 2, we borrow two; in base 8, we borrow eight; and in base 16, we borrow sixteen.
- To subtract 1001₂ − 11₂, first rewrite 11₂ as 0011₂ so both numbers have the same length. Start subtracting from the right: 1 − 1 = 0. Next, 0 − 1 is not possible, so borrow from the left. In base 2, borrowing gives a value of 2, so 2 − 1 = 1. Continue with 1 − 0 = 1 and 0 − 0 = 0. The result is 0110₂, which is 110₂.
