    63-53

  6. 63-42

  7. 63-12

  8. I wonder if anyone from a middle school background wrote 63 – (-5). It meets the qualifications.

  9. 63-12, since there are less ones in 12 then 63 i do not have to regroup

  10. 63-41 would not require regrouping because the number to subtract has a value in both the ones and tens place that is less than the greater number. 1 < 3 and 4 < 6 This way no regrouping is required to solve the problem.

  11. 63-23. No need to regroup since there are two 3’s in the ones place that will give a 0 and in the tens place you have 6-2, which will give a 4

    I need to make sure i am subtracting numbers less than the number in each place value.

  13. 63-23
    Ones place must have a number that is the same or less value so you won’t have to rename/regroup

  14. 63-52

  15. 63-21
