### Basic Math

#### Percent Error Calculator

Percent error calculator is a free and easy-to-use tool that displays the percentage error. This tool mainly to present error is also called a percentage error, which defines the difference between the observed and true value expressed in percentage. In short, the percentage error is a relative error that has multiplied by 100. Furthermore, the percentage error has generally been calculated to the locate the big errors during the analysis process. by the given formula.

Percentage Error = [ (True value – observed value) / True value ] × 100

#### Hex Calculator

### Statistics

#### Probability Calculator

Calculating probability means you are counting to figure out some important event happening. Probability is one kind of different calculator that can be applied to various applications. Probability Calculator is a tool that you can use as an online tool to calculate single and multiple events based on several possible events and outcomes that occurred. There are mainly two types named theoretical probability & experimental probability. This tool is used in several industries to develop mathematical models.

#### Mean, Median, Mode, Range Calculator

These are the most popular summarizing analysis used to describe a data set using one or several numbers. That means mode and median can all be called an "average" in specific literature, but using their proper technical names is recommended to avoid confusion. Adding "number-crunching" likewise helps, since there is a mathematical mean, a symphonious mean, a mathematical middle, and so on, and it isn't in every case promptly obvious from setting which one you are alluding to. In like manner, English "normal" and even "signify" can be utilized as equivalents to "regular", which can be exceptionally deceptive much of the time where the circulation is slanted or scattered (see the model underneath). We are simply calling them by their short name in our mean, middle, mode and reach number cruncher. Here are short definitions and when each is generally suitable, and models dependent on the arrangement of numbers: 1, 2, 3, 3, 5, 10, 18, 20, 28

#### Matrix Calculator
