$$ 60 + 17 $$ What is the sum of the tens digits?

If the sum of the tens is $7$ in an addition problem, what number do you write in the tens place of the answer?

You write a $7$.

After you add the ones column, which column do you add next?

You add the tens column next.

In the problem $52 + 36$, what are the two digits in the tens place?

The digits are $5$ and $3$.

$$ 52 + 36 $$ What is the sum of the tens digits?

$$ 5 + 3 = 8 $$

It represents $8$ tens, or $80$.

In the problem $71 + 25$, what is the second addition step?

Add the tens: $7 + 2 = 9$.

$$ 43 + 43 $$ What is the sum of the tens digits?

$$ 4 + 4 = 8 $$

$$ 28 + 61 $$ What is the sum of the tens digits?

$$ 2 + 6 = 8 $$

$$ 15 + 82 $$ What is the sum of the tens column?

$$ 1 + 8 = 9 $$

$$ 33 + 54 $$ After adding the ones, what is the next calculation you perform?

Add the digits in the tens column: $3 + 5$.
