Question

which expression will be easier to simplify if you use the associative property to change the groupingA.[-12+(-5)]+36B.[21+(-14)]+(-53)C.67+[3/2+(-1/2)]D.(70+30)+72

Answer 1

The expression:

[21+(-14)]+(-53)

will be easier to simplify using associative property as follows:

21 + [(-14) + (-53)]

So that, the two negative numbers are combined first.
