加减题生成器 2.1.5

As a parent of a first-grade elementary school student, I often need to practice various basic addition and subtraction operations, so I frequently search for and download relevant materials. However, some common types of arithmetic problems are not easy to find, and downloading them can be quite cumbersome. That's why this tool was developed, and currently, the developer themselves uses it every day. The main features are as follows:

1. Support for quickly generating different types of math problems, including common addition and subtraction operations within 10, 20, and 100.
2. Freedom to choose the number and format of generated problems.
3. Output results in PDF format for easy sharing and printing.

A recent addition to the tool is the function for correcting exercises by taking photos. Feel free to try it out!

It's essential for children to practice math every day, but finding new exercises daily can be cumbersome. I hope this app can assist you in this regard. If there are areas for improvement, please provide constructive feedback to facilitate continuous development. Thank you!
