How to add and subtract fractions and mixed fractions with and without regrouping?

If you’ve learned the mixed fraction addition and subtraction techniques in the previous sections, you should be able to add and subtract these without any problems. If you need to regroup the denominators first, take your mixed fraction and add one to the bottom of the fraction. This will make the mixed fraction easier to add with your other fraction.

How to subtract fractions and mixed fractions without regrouping?
