Here are the solutions to the mathematics problems from the image.

: Use any method to calculate the following.

Add the tens digits
$7 + 8 = 15$ . Write 5, carry 1.
Add the hundreds digits
$5 + 9 + 1 (\text{carry}) = 15$ . Write 5, carry 1.
Add the thousands digits
$3 + 2 + 1 (\text{carry}) = 6$ . $3572 + 2981 = \boxed{6553}$ 3. Step 1: Add the ones digits: $5 + 5 = 10$ . Write 0, carry 1.
Add the tens digits
$1 + 8 + 1 (\text{carry}) = 10$ . Write 0, carry 1.
Add the hundreds digits
$7 + 2 + 1 (\text{carry}) = 10$ . Write 0, carry 1.
Add the thousands digits
$6 + 0 + 1 (\text{carry}) = 7$ . $6715 + 285 = \boxed{7000}$ 5. Step 1: Add the ones digits: $2 + 5 = 7$ .
Add the tens digits
$6 + 2 = 8$ .
Add the hundreds digits
$5 + 8 = 13$ . Write 3, carry 1.
Add the thousands digits
$4 + 3 + 1 (\text{carry}) = 8$ . $4562 + 3825 = \boxed{8387}$ 7. Step 1: Add the ones digits: $7 + 4 = 11$ . Write 1, carry 1.
Add the tens digits
$4 + 8 + 1 (\text{carry}) = 13$ . Write 3, carry 1.
Add the hundreds digits
$9 + 3 + 1 (\text{carry}) = 13$ . $947 + 384 = \boxed{1331}$ 9. Step 1: Add the ones digits: $6 + 3 = 9$ .
Add the tens digits
$7 + 5 = 12$ . Write 2, carry 1.
Add the hundreds digits
$3 + 7 + 1 (\text{carry}) = 11$ . Write 1, carry 1.
Add the thousands digits
$8 + 4 + 1 (\text{carry}) = 13$ . $8376 + 4753 = \boxed{13129}$

: Replace the letters with the correct numbers.

The image provides the solutions for 'a' and 'b' in the number pyramid examples.
- For 'a', the calculation shown is $3231 - 1647 = 1584$ . This is correct.
- For 'b', the calculation shown is $2131 + 1252 = 3383$ . This is correct.
