It is zero.
It is zero.
Zero is a real number, it is neither positive or negative, and it is even.
no. Because square of zero is neither positive nor negative.
If you square any real number it will always be positive.
A negative (real) number multiplied by a positive (real) number will always result in a negative (real) number.
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
Real numbers are composed of rational and irrational numbers. Integers are part of the group (set) of rational numbers. And the integers are composed of the counting numbers (1, 2, 3, ...) and their negative counterparts (-1, -2, -3, ...). Oh, almost forgot. There is one more integer that is neither positive or negative. It's the number zero. Zero is an integer (neither positive or negative). The smallest real number ever is zero.
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
With the exception of zero, which is neither positive nor negative, every real number is either plus or minus. With positive number, the + sign is often implied and therefore is not always written [example: 3 and +3 both mean positive three]
Negative and positive
there is no real life situation
