About this app

Having trouble in Math? Especially in understanding and solving numerical expressions? Now you have at your disposal an app to help you!

The Numerical Expressions consists of a calculator capable to solve, analyze and generate the binary tree of any expression. Furthermore, the app features visual aids that highlight parentheses from expressions, facilitating the visualization of resolving priorities in an expression.

The following is a detailed description about the app's features:

- Get the resolution of the numerical expression
Enter any numerical expression and get its resolution.

- Show implicit parentheses
Implicit parentheses are those who were not informed when entering the expression, but it is as if they were present to justify the natural precedence of operators.
For example: in the expression 4 + 6/2, as the division operator "/" has higher priority than the addition operator "+", we can say that this expression has a pair of implicit parentheses. If we display them, the expression would look like this: 4+ (6/2).

- Highlight pairs of parentheses
It is possible to highlight each pair of parentheses in a different color, or even the entire content inside them.

- View step by step resolution
See each of the calculations performed in the expression to get the final result.

- Get the binary tree of the expression
The binary tree is a data structure. In this case is used to graphically represent the expression, identifying unambiguously the order in which the sub-expressions must be solved. Facilitating the understanding of operator precedence.

- Analyze the expression
Learn about each of the expression’s components (numbers, operators or other symbols).

You will also have at your disposal a short content divided into the following topics:

- Operators
Get information about each operator along with examples.

- Operator precedence
See a table of easy understanding that display the operator precedence.

- Numbers
Get information about the types of numbers that may appear in numerical expressions.

- Higher priority delimiters
Read a brief description about each higher priority delimiter and how to use them.

Disclaimer:
Each informed expression is automatically calculated, wrong results may be returned.

New features

- Removed the size limit of the numerical expression
- Included processing indicator while expression is calculated
