# 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://todarith.ml/generate/
To try out generators, go to <https://todarith.ml/generate/>
If you have an idea for a generator, please add it as an issue and tag it with the "New Generator" label.
## Usage
The project can be install via pip
```
```bash
pip install mathgenerator
```
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()
```
