# How to calculate the equations with AxMath?

AxMath’s calculator has most of the commonly used scientific calculating capabilities, such as arithmetic, exponential, logarithmic, trigonometric, permutations and so on. The calculator works purely based on equation. It is a WYSIWYG and intuitive calculator and can be used to replace those desktop key-style scientific calculators completely.

## Usage

When you have typed lines in the workspace like:

Press the trigger key (equal sign ‘=’ by default), AxMath will calculate the value of and fill the result at the end automatically, as shown below:

The first line, of the above example, defines a variable named d, and with a value of 32. The second line contains the constant π approximately equaling to 3.1415926. The calculation result is the area of a circle with a diameter of 32, and it can be cited as another variable, represented by the A, in the following lines if you will.

You can save such a procedure to a file, and re-open it when necessary, then change the value of the variables and run it all again by using the entry “Calculate All Lines” of the context menu, or the hotkey F6.

If you have some calculation tasks that are repetitively used and with long procedure, AxMath will save you a lot of time.

Note: You can disable the calculation by the check button in the “Calculator” tab of the “AxMath Settings” dialog if you do not need it.

## Constants

You can define constants in the “Calculator” tab of the “AxMath Settings” dialog. A legal constant must be a string started with a character and can not has sub/sup script or accents.

## Variables

Unlike the constants, A legal variable of AxMath must be one character and can has sub/sup script or accents. For examples:

The variables are defined in the workspace. You can type more than one variable definition in one line and separate them from each other using commas.

## Units

AxMath’s calculator knows no idea about physical units. The user must have the system of units in his mind when do a calculation using AxMath.

When you define a varibale of angle, the default unit is rad. If you want define a angle using degree/minute/second, type the unit symbols after the numbers, like:

Here the variable α has the same value with β.

## Conclusion

You may already astonished by Semantic Math IME in previous articles, but there’s much more. AxMath is also a scientific calculator. You can define symbol’s numeric values and once you type a expression and enter “=”, AxMath will automatically gives you the result.
