Addition is simpler than subtraction. Also, it is defined as the opposite of subtraction, so this ... opposite has to be taught first.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is difference in algebra?

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.

Draw the flowchart and explain arithmetic addition and subtraction algorithm with example?

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.

What is the main limitation of sign magnitude representation?

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.

Why is The product of a negative integer and a positive integer is always negative integer?

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 (&minus;3), which means "4 times negative &minus;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.

Carry flag and over flow flag in 8051?

Carry flag is the the bit 7 of the 8 bit PSW register, whenever there is an addition or subtraction process that has a carry on its 7th bit, the carry flag (C/CY) will be set to 1. OV is set to 1 when there is an arithmetic overflow. this applies to signed and unsigned operations.

Working of difference engine?

Mechanical implementation of the solution of a difference equation (discrete version of differential equation). It does repeated additions of one value to the next value. With proper analysis and programing it can solve any polynomial equation that fits on the machine. Using a 10s complement signed number representation addition could also simulate subtraction.
