**The real numbers**include

**all the**rational

**numbers**, such as

**the**integer −5 and

**the**fraction 4/3, and

**all the**irrational

**numbers**, such as √2 (1.41421356,

**the**square root of 2, an irrational

**algebraic number**). Included within

**the**irrationals are

**the**transcendental

**numbers**, such as π (3.14159265).

In this way, what are the real numbers in math?

The **real numbers** include integers, rational, and irrational **numbers**. The **number** line contains all the **real numbers** and nothing else. Every **real number** has a decimal representation.

Beside above, what is real no with example? A **real number** is any positive or negative **number**. This includes all integers and all rational and irrational **numbers**. For **example**, a program may limit all **real numbers** to a fixed **number** of decimal places.

Beside this, what is not a real number in algebra?

A **non**-**real**, or imaginary, **number** is any **number** that, when multiplied by itself, produces a negative **number**. Mathematicians use the letter "i" to symbolize the square root of -1. An imaginary **number** is any **real number** multiplied by i. For example, 5i is imaginary; the square of 5i is -25.

Is 0 a real number in math?

Yes, **0** is a **real number in math**. Furthermore, **0** is a whole **number**, an integer, and a rational **number**. Since the **real numbers** include all of these types of **numbers**, we know that **0** is included in the set of **real numbers**, solidifying the fact that **0** is a **real number**.
