Answer 2

Answer:

Step-by-step explanation:

543 + 89

from the 3 and 9 split 9 to get a ten with the 3: 3 + 7 + 2 so 2 goes into the units category of the answer:

..2

Now as 9 > 3 we add 1 to the tens digit

- that is 8 becomes 9.

from the 4 and 9 split 9 to get a ten with  the 4: 6 + 3 so 3 goes into the tens category:

.32.

Now as 9 > 4 we add 1 to the 5, so the answer is 632.
