描述
The opposite-change rules states that if you subtract a number from one addend and add the same number to the other addend, the sum remains the same. An addition problem 267 + 289 is easier to solve when it has been changed into 256 + 300.
Features:
- The numbers can have up to 3 digits
- You can set your own problems
