its cuz ur ugly........
The signs use an exclusive OR gate where if the output is 0, then the signs are the same.Hence, add the magnitudes of the same signed numbers. If the sum is an overflow, then a carry is stored in E where E = 1 and transferred to the flip-flop AVF, add-overflow.Otherwise, the signs are opposite and subtraction is initiated and stored in A.No overflow can occur with subtraction so the AVF is cleared.If E = 1, then A > B.However, if A = 0, then A = B and the sign is made positive.If E = 0, then A < B and sign for A is complemented.
Signed numbers are "plus" and "minus" numbers.
Positive signed numbers with have a + Positive integers will not.
The range for signed numbers is -128 to +127. The range for signed numbers is 0 to 255.

Addition is simpler than subtraction. Also, it is defined as the opposite of subtraction, so this ... opposite has to be taught first.
i'm so sorry... i don't know also...
Most operations may be carried out on signed numbers: addition, subtraction, multiplication, division, exponentiation, trigonometric functions and so on. For some operation the domain may need to be restricted (or the codomain extended).

One of the bit patterns is wasted. Addition doesn't work the way we want it to. Remember we wanted to have negative binary numbers so we could use our binary addition algorithm to simulate binary subtraction. How does signed magnitude fare with addition? To test it, let's try subtracting 2 from 5 by adding 5 and -2. A positive 5 would be represented with the bit pattern '0101B' and -2 with '1010B'. Let's add these two numbers and see what the result is: 0101 0010 ----- 0111 Now we interpret the result as a signed magnitude number. The sign is '0' (non-negative) and the magnitude is '7'. So the answer is a postive 7. But, wait a minute, 5-2=3! This obviously didn't work. Conclusion: signed magnitude doesn't work with regular binary addition algorithms.
The difference between two numbers is the smaller number subtracted from the larger. This is the absolute value of the first number minus the second number. However, sometimes the term is used for the signed subtraction.

The rules for multiplying signed numbers may be formulated from the fact that multiplication serves as a shorthand notation for addition. For example, 4 x (−3), which means "4 times negative −3" is the same as the following: (-3) + (-3) + (-3) + (-3) = -12 Therefore, it follows that multiplication of a negative and positive number represents addition of negative numbers.
