Questions
How is this different from the "2-digit with regrouping" sheet?
There, every problem carries. Here about half do, which is how problems come in real tests and is the better practice once the method is known.
Can I add subtraction to the same sheet?
Yes. Set Operation to "Mixed": problems alternate between addition and subtraction with the same number size.
