The SUMA
mathematical operation has several properties, among them the Commutative that
establishes "The order of the addends does not alter its result"
Let's develop the
calculations for both students :
A (Scott) = 1 / 2
(24 + 16) (8) = 1 / 2 (40) (8) = 160
A (Tare) = 1 / 2
(16 + 24) (8) = 1 / 2 (40) (8) = 160
On the basis of
this Commutative Property of the sum, which the students applied ; Both Scott
and Tara have responded correctly.
