Today I used the part adder to solve two digit numbers. I had to solve 48 + 49. I split the 49 and split the tens and ones into 40 + 2 + 7. Then I add 48 + 40 and my answer is 88. Then I added 88 with 2, which gives me 90. Finally I added the 7 and got my answer, 97.
For this way I split the 48 into 37 and 11. Then I added 11 with 49 and got 60. Then I added 37 with 60 and got my final answer, 97.
