Real numbers are all positive numbers except zero.
Any positive number can be written as a quotient of two positive numbers or a quotient of two negative numbers. Any real number can be written as the quotient of two real numbers.
No, the product of two negative numbers is always a positive.
Positive numbers are greater than zero and negative numbers are less than zero. They are both collectively referred to as real numbers.
Not at all. The class of "natural" numbers are all positive, but the classes of "real" numbers and "rational" numbers include negative numbers.
Real numbers are all positive numbers except zero.
Yes. Real numbers include positive and negative numbers, integers and fractions, rational and irrational numbers.
Any positive number can be written as a quotient of two positive numbers or a quotient of two negative numbers. Any real number can be written as the quotient of two real numbers.
No, the product of two negative numbers is always a positive.
Positive numbers are greater than zero and negative numbers are less than zero. They are both collectively referred to as real numbers.
For the same reason that the square root of ANY negative number is not a real number.Real numbers are positive, negative, or zero. * The square of a positive number is a positive number. * The square of a negative number is a positive number. * The square of zero is zero. In other words, in no case will you get a REAL number whose square is a negative number. The square roots of negative numbers are said to be "imaginary" - a name given for historical reasons. They are just as "real" or "unreal" as the so-called real numbers, but the point is that they are a different kind of numbers.
Not at all. The class of "natural" numbers are all positive, but the classes of "real" numbers and "rational" numbers include negative numbers.
When two negative real numbers are multiplied together, the product is a positive real number.
Negative number and positive numbers are all numbers. Negative numbers are just positive numbers multiplied by -1.
Natural numbers extend from 1 to positive infinity.Real numbers are all numbers between negative infinity and positive infinity.ALL natural numbers are real numbers, but NOT ALLreal numbers are natural numbers.
Yes, real numbers include both positive and negative numbers. They also include whole numbers and fractional numbers, as well as irrational numbers (numbers that can't be expressed as the ratio of two whole numbers).
The set of non-zero real numbers.
