Is negative 3 a real number?
Yes negative 3 is a real number. 0 is the only number which...isn't a number. The is a political debate going on at the moment debating this particular topic!!!
Is 0 a real number?
NO, negative numbers are though. 0 is more like a placeholder. It's not a actual number. It CAN be a digit, though! Love, :D
If A and B are real numbers and A is less than 0 and B is less than 0 then is AB less than or greater than 0?
Greater than zero because any negative number times a negative number equals a positive number.
If the square root of a rational number X was divided by another rational number Y and the result would be undefined what could be the possible values of X and Y?
probably x would be negative. This is because the square root of a negative number is not a real number (no real number squared can be negative). ory is 0. any number divided by 0 = infinity. and undefined is another way of saying infinity.
Is 0 an imaginary number?
This is an interesting question. Looking at complex numbers graphically, zero is at the intersection of the real and imaginary axis, so it is 0 + 0i. But if you square zero, you get zero, which is not a negative number (a pure imaginary, when squared will give a real negative number), so I'd have to say it is not imaginary.
What is a negative numbers?
A real number that is less than 0.

What is the product of 9 negative real number?
The product of nine negative real numbers is a negative real number.
Is -20 an real number?
yes. it is negative. a negative number is a real number
A negative times a postitive gets you?
A negative (real) number multiplied by a positive (real) number will always result in a negative (real) number.

If the exponent on a negative number is 0 is the number positive or negative?
Any positive number to the 0th power is one. ex. (51^0 = 1) Any negative number to the 0th power is negative one. ex. (-23^0 = -1) The exception is 0. 0^0 = 0
Is the number 0 a positive or negative number?
0 is neither a positive nor negative number. neither
Explain why the roots of a quadratic equation are imaginary if the value of the discriminant is less than 0?
The square of any real number is non-negative. So no real number can have a negative square. Consequently, a negative number cannot have a real square root. If the discriminant is less than zero, the quadratic equation requires the square root of that negative value, which cannot be real and so must be imaginary.
