What else can I help you with?
Are irrational numbers a part of the real number system?
Yes.
Do negative numbers exists?
Yes, negative numbers do exist and are an integral part of mathematics. They represent values less than zero and are used in various contexts, such as accounting, temperature measurements, and financial calculations. Negative numbers help in understanding concepts like debt and loss, making them essential for a complete understanding of the number system.
Why is a real number is a component of the real number system?
It would be a bit stupid to call a system the real number system if real numbers were not a part of it!
Do integers numbers have decimals?
No, integers are whole numbers that do not have any decimal or fractional parts. Integers include positive numbers, negative numbers, and zero. Decimals are used to represent numbers that fall between integers on the number line.
What is real about real numbers?
These numbers are real in contrast to complex numbers which contain an element which is called imaginary. All this arises because the square of any "normal" number is non-negative. So it is not possible to take the square root of a negative number. In some cases, though, there are mathematical advantages in being able to do so. So mathematicians introduce i, the square root of -1. Numbers involving i are said to be imaginary and, by way of contrast, those that don't, are said to be real. A number comprising a real part and an imaginary part is called a complex number.

Are all whole numbers positive numbers?
Yes, EXCEPT for the number 0. It is a whole number but is not positive or negative. Real Numbers - Everything I. Rational Numbers- Any number except for non terminating decimals A. Integers- Any negative or positive number...not a decimal1. Whole Numbers- Any positive integer INCLUDING ZEROa. Natural Numbers- Any positive integer (NOT INCLUDING ZERO) The answer is not entirely correct, Whole numbers are numbers without a fractional part or decimal point. Therefore whole numbers can be negative as well as positive. -2 is a whole number but is not positive. There are a number of different interpretations for whole numbers, from non-negative integers, positive integers and all integers (which includes negative integers)
What are the sets of numbers that are part of the complex number system?
Real number set, imaginary number set, and their subsets.
Are positive numbers whole numbers?
No. Positive numbers can be whole numbers but they can also be decimal numbers and fractions. If a value is a whole number, it does not have a fraction or decimal part and it is not negative. Whole numbers are also called natural numbers or counting numbers.
Is -4 a imaginary number?
No, both positive and negative numbers are part of the so-called "real" numbers. The so-called "imaginary" numbers are outside the number line.Imagine the real numbers as a line from left to right, and the imaginary numbers a a separate line, from top to bottom. The place where they meet is zero. Positive is to the right of zero, negative to the left, imaginary numbers like +i or +3i to the top of zero, and negative imaginary numbes like -5i to the bottom of zero.
What is the smallest real number ever?
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.
What set of numbers does -6 belong to?
Oh, dude, -6 belongs to a few different sets of numbers. It's a whole number, an integer, a rational number, and a real number. So, like, it's basically part of the big happy family of numbers.
Do integers numbers have decimals?
No, integers are whole numbers that do not have any decimal or fractional parts. Integers include positive numbers, negative numbers, and zero. Decimals are used to represent numbers that fall between integers on the number line.
What real number is less than -1?
Many options - e.g. -2"Real number" means all the numbers we know, including positive and negative numbers.The only numbers that are not included are "imaginary numbers" - numbers that have an imaginary part i (used only i physics or high mathematics).See real-number

Can a whole number be negative?
It seems to vary depending on who you ask. The definition of the set of whole numbers always includes the positive integers. However, it may also include zero and possibly the set of negative integers.
