• Integers: These are real numbers that have no decimals.

## Which are the real numbers?

Real numbers are the numbers which include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

## What are examples of not real numbers?

Imaginary numbers are numbers that cannot be quantified, like the square root of -1. The number, denoted as i, can be used for equations and formulas, but is not a real number that can be used in basic arithmetic. You cannot add or subject imaginary numbers. Another example of an imaginary number is infinity.

## What is the difference between natural and real numbers?

): The counting numbers {1, 2, 3.} are commonly called natural numbers; however, other definitions include 0, so that the non-negative integers {0, 1, 2, 3.} are also called natural numbers. All rational numbers are real, but the converse is not true. Irrational numbers: Real numbers that are not rational.

## Is the number 1 a real number?

The type of number we normally use, such as 1, 15.82, −0.1, 3/4, etc. Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers. They are called “Real Numbers” because they are not Imaginary Numbers.

## Which is greatest number?

To get the greatest number, the greatest digit 9 is placed at the highest valued place, i.e., thousands-place, next smaller digit 6 at hundreds-place, still smaller digit 5 at ten’s place and the smallest digit 2 at one’s or units place. Thus, the greatest number is 9652.

## What type of number is I?

Imaginary Numbers When we square an imaginary number, it gives a negative result, which means it is a square root of a negative number, for example, √-2 and √-5. When we square these numbers, the results are -2 and -5. The square root of negative one is represented by the letter i, i.e.

## Is 9 a whole number?
