9. The column by column addition of numbers can
be justified as follows. State the property of the
whole numbers that justifies each of these steps.
We begin with expanded notation.
36 +52 = (3-10 + 6) + (5 10 + 2)
3 10+ [6+ (5 10+ 2)]
-
= 3 ⋅ 10+ [(6 + 5 10) + 2]
10+ [(5 10 + 6) + 2]
= 3
= 3 10+ [5
10 + (6 + 2)]
= (3 10+5
10) + (6 + 2)
= (3 + 5) 10 + (6 + 2)
= 8-10 + 8
= 88
