use the associative property to write two expressions that you could use to find each sum.
add 5,91,and 11

The associative property of addition is simply:

$(a + b) + c = a + (b + c)$

So 5 + 91 + 11 = (5 + 91) + 11 = 96 + 11 = 107

or 5 + 91 + 11 = 5 + (91 + 11) = 5 + 102 = 107

I'm assuming that's the 2 they're after.
