Pasted from the comments above the initial post, I put them there first before I realized I could add my own post...

Method 1:
71+84 = (70+80) +(1+4) = 150 + 5 = 155

Method 2: (vertical columns) add the ones first, getting 5 - then add the tens, getting 150, so the total is 155 apples

# data[].attributes.body
31+ 34
30 apples + 30 apples = 60 apples
4 apples +1 apple =5 apples
60 apples + 5 apples = 65 apples

31+ 34
30 apples x 2 = 60 apples
+ 5 apples (because 4+1 =5)
= 65 apples
