**What is the difference among BINARY, HEXADECIMAL, and DECIMAL?**

Binary: “In mathematics and computer science, the **binary numeral system**, or **base-2 numeral system**, represents numeric values using two symbols: typically 0 and 1. More specifically, the usual base–2 system is a positional notation with a radix of 2. Numbers represented in this system are commonly called **binary numbers**. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices such as mobile phones.”

Hexadecimal: “In mathematics and computer science, **hexadecimal** (also **base 16**, or **hex**) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols **0**–**9** to represent values zero to nine, and **A**, **B**, **C**, **D**, **E**, **F** (or alternatively **a**–**f**) to represent values ten to fifteen. “

Decimal:

The **decimal** numeral system (also called **base ten** or occasionally **denary**) has ten as its base. It is the numerical base most widely used by modern civilizations.^{[1]}^{[2] }**Decimal notation** often refers to a base-10 positional notation such as the Hindu-Arabic numeral system; however, it can also be used more generally to refer to non-positional systems such as Roman or Chinese numerals which are also based on powers of ten. **Decimals** also refer to decimal fractions, either separately or in contrast to vulgar fractions. In this context, a decimal is a tenth part, and decimals become a series of nested tenths. There was a notation in use like ‘tenth-metre’, meaning the tenth decimal of the metre, currently an Angstrom. The contrast here is between decimals and vulgar fractions, and decimal divisions and other divisions of measures, like the inch. It is possible to follow a decimal expansion with a vulgar fraction; this is done with the recent divisions of the troy ounce, which has three places of decimals, followed by a trinary place.

**“Inductive reasoning** is reasoning in which the premises seek to supply strong evidence for (not absolute proof of) the truth of the conclusion. While the conclusion of a deductive argument is supposed to be certain, the truth of an inductive argument is supposed to be *probable*, based upon the evidence given.”

I think that it was a great experience
