# mathgenerator
A math problem generator, created for the purpose of giving self-studying students and teaching organizations the means to easily get access to random math problems to suit their needs.
To try out generators, go to <https://lukew3.github.io/mathgenerator>
See [CONTRIBUTING.md](https://github.com/lukew3/mathgenerator/blob/main/CONTRIBUTING.md) for information about how to contribute.

## Installation
The project can be install via pip
```bash
pip install mathgenerator
```
## Basic Usage
Here is an example of how you would generate an addition problem:
```python
from mathgenerator import mathgen
#generate an addition problem
problem, solution = mathgen.addition()
#another way to generate an addition problem using genById()
problem, solution = mathgen.genById(0)
```
### Creating a worksheet
If you wish to create a worksheet, you can use the [worksheetgen](https://github.com/lukew3/worksheetgen) package. Install this with `pip install worksheetgen`. Here is an example of how a worksheet would be generated.
```
from mathgenerator import mathgen
from worksheetgen.wg import Worksheet
worksheet = Worksheet("Worksheet title")
worksheet.add_instruction("Instructions")
# Writes 10 problems generated with id 1, [0] at the end specifies to take problem, and not solution.
for _ in range(10):
worksheet.add_problem(mathgen.genById(1)[0])
worksheet.write_pdf()
```
This creates the pdf `ws.pdf` in your current directory
## Documentation
* `getGenList()` returns a list of all generators in the repository in the format `[id, title, self, funcname, subjectname]`
* `genById(id)` generates a problem, solution set with generator id `id` in the format `[problem, solution]`
* Pass the kwarg `format=latex` to return problem and solution set as latex. If latex is not available for that generator, the problem will return the string "Latex unavailable"
* Pass the kwarg `format=raw` to return just the raw data for each generator. An array of each variable necessary to the generator is returned.
