Yes, -1 and 1 are real numbers.
Real numbers consist of Irrational Numbers, rational numbers and integers.
Yes they are real numbers
The unit for real numbers is the number 1.
Natural numbers, integers, rational numbers are all part of the real numbers. -1 is an integer (and a rational number), so it is also real.
Yes. :S real numbers are real numbers. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Real numbers are those which can be placed upon a number line stretching to infinity in both directions. To be "not real" you must be unable to do that. We call "not real" numbers "imaginary" numbers. They are numbers which are derived from the square root of -1. If you think about it, what number can be multiplied by itself and you end up with -1. In the real numbers, there isn't one. So we have imaginary numbers. They are written using Euler's notation where i represents the square root of -1. So, to answer your question, i is a "not real" number.
A real number is a number that can be expressed as a decimal of some form. The integers: -2, -1, 0, 1, 2 The rational numbers: 2 1/2, 3.45, 2/3 The irrational numbers: pi, square root of 5, e, 5.8283851920493809... These are all real numbers. Imaginary numbers: i, 5i, 3i + 2, 4i - 3 These are not real numbers.
Real numbers are all numbers which do not contain "i", when "i" represents the square root of -1. All numbers which do contain "i" are "imaginary numbers" and are not real numbers. This means that all numbers you'd ordinarily use are real numbers - all the counting numbers (integers) and all decimals are real numbers. So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers - including irrational decimals such as pi.
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.
Integers, odd integers, negative integers, odd negative integers, rational numbers, negative rational numbers, real numbers, negative real numbers, square roots of 1, etc.
It is an element of the set of real numbers.
It is 1, as it is for all complex numbers - which includes real numbers.
Probably because if you consider real numbers, you are not interested in complex numbers.Any complex number other than zero - and that includes real numbers - has three cubic roots, which have an angle of 120 degrees between one another. For example, the cubic roots of 1 are 1, 1 at an angle of 120°, and 1 at an angle of 240°. Similarly, the cubic roots of -1 are 1 at an angle of 180° (equal to -1), 1 at an angle of 60°, and 1 at an angle of 300°.
Yes, 3.5 is real number.Real numbers include all numbers except complex numbers which are of the form a+ib where a & b are real numbers and i = -11/2
All real numbers, except 0, have a multiplicative inverse. For any real x, (x not = 0), there exists a real number y such that x*y = 1. This y is denoted by 1/x.
Not whole numbers. Yes to real numbers and integers.
All of them. Real numbers are a subset of complex numbers.
NO for Integers NO for Real Numbers proof 1 * any integer is not bigger than that integer nor is 0 * any integer. proof for Real Numbers is easier any real < 1 * any real > 0 is not larger than the second Real for example .5 * 1 = .5 is less than 1 or .5 * 2 = 1 less than 2 or .5 * = 1 less than 2 or -1 *3 = -3 less than 3 so all fractions times a positive Real is less than that positive Real All negative numbers times a positive Real is less than that positive Real and 0 or 1 times all positive Reals is also less than that positive Real NO NO NO is the answer
From 1 to 100 there are 100 integers, but an infinite number of real numbers.
There are an almost infinite number of real numbers between 0 and 1.
There are mathematical concepts that mathematicians call "imaginary numbers" these are a multiple of the square root of minus 1. Infinity is not a real number either.
Most numbers are real numbers, but they are called that to distinguish them from imaginary ones. The best example of an imaginery number is the square root of minus 1. This is not a possibility.
Yes, all natural numbers are real numbers. Natural numbers are a subset of real numbers, so not all real numbers are natural numbers.
