Please Help! I will give you a lot of points and the brainiest! --This is Hindu-Arabic math, so you can't use our regular number system

5613 (base 9)
+ 3678 (base 9)

Starting in the 1s column:
3+8 = 11 (base 10), so in base 9, that’s “2 carry the 1” because 11 is 2 more than 9.

In the next column:
1+7+ the 1 that was carried = 9 (base 10), so in base 9 you put a 0 and carry the 1

Next column:
6+6+1 = 13 (base 10), so in base 9 you put 4 and carry a 1, because 13 is 4 more than 9

Next column:
5+3+1 = 9 (base 10), so in base 9, you put 0 and carry a 1 to the next column

See the picture for the written work. The left part just shows the first step, while the right picture shows the entire answer.

Can you provide the tape diagram?
