描述
The same-change rules states that If you subtract or add the same number from both parts of a subtraction problem, the difference remains the same. A subtraction problem 667 – 289 is easier to solve if it is changed into 678 – 300.
Features:
- The numbers can have up to 3 digits
- You can set your own problems
