The built-optimized model for this type of captcha is using ONNX.
The Open Neural Network Exchange is an open-source artificial intelligence ecosystem of technology companies and research organizations that establish open standards for representing machine learning algorithms and software tools to promote innovation and collaboration in the AI sector. ONNX is available on GitHub.

This screenshot is an example of the results obtained from the 20 captcha images shared for you
As you can see in the picture, there are some mistakes in the results.
For example, in some images, the program calculates the answer incorrectly due to the similarity between the words یازده and پانزده.
If you are make a web script using seleinum or other tools that uses this library, you can solve this problem by creating an error handling or try , except block.
For example, in 15+8=23 :
If the 23 entered on the web page was wrong, use the extracted_text variable to replace the number 11 with the number 15 and calculate the answer again.
