The definition for the standard form of decimal numbers is the same as that of whole numbers, **Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10**, is said to be in standard form.

The most commonly used numeral system is the **decimal positional numeral system**, the decimal referring to the use of 10 symbols—0, 1, 2, 3, 4, 5, 6, 7, 8, 9—to construct all numbers.

**11** (number), XI in Roman numerals.

Like wise, other numbers can be written with the help of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Thus, we can regard **0, 1, 2, 3, 4, 5, 6, 7, 8, 9** as basic numerals.

Imaginary numbers, also called complex numbers, are used in real-life applications, such as **electricity, as well as quadratic equations**. In quadratic planes, imaginary numbers show up in equations that don't touch the x axis. Imaginary numbers become particularly useful in advanced calculus.

**The number 5 is present in the real numbers**. Therefore, the number 5 is a rational, whole, integer and real number.

Real numbers can be thought of as an **infinitely long ruler**. There is a mark for zero and every other number, in order of size. Unlike a physical ruler, there are numbers below zero. These are called negative real numbers.

A logarithm **tells what exponent (or power) is needed to make a certain number**, so logarithms are the inverse (opposite) of exponentiation. Historically, they were useful in multiplying or dividing large numbers.
