max donated 16 collars to the dog shelter . Mia donated some leashes. hiw many items does Mia need to donate that would require you to regroup to find the total number of items donated?

If we add 16+4, we must carry (regroup). This is because 6+4 = 10, so we carry 1 to the tens place. This is the first time we would regroup this number.

To regroup is another term used for "carry" in arithmetic operations

The least number of items Mia would add, that would require regroup is 4

From the question, we have:

[tex]Max= 16[/tex]

When 1, 2 or 3 are added to 16, there is no "carry" operation.

Because, they are all straight addition operations

[tex]16 + 1 = 17[/tex]

[tex]16 + 2= 18[/tex]

[tex]16 + 3 = 19[/tex]

However, when 4 is added to 16, there is a need to regroup.

The addition is illustrated as follows:

[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\&&\end{array}\right][/tex]

Add 6 and 4;

The result is 10.

So, we write down 0, and "carry" 1

[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\&0&\end{array}\right][/tex]

Next, add 1 (the one beside 6) to the 1 we carried in the previous addition

The result is 2

[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\2&0&\end{array}\right][/tex]

The process of "carrying" is what is referred to as regroup

So, the least number of items Mia would add, that would require regroup is 4
