Question

8 + 7 = 15

Answer 1

For this case, we have the following generic expression:

$a + b = c$

The commutative property of the addition states that the order of the addends does not alter the sum, therefore the previous expression above can be written as:

$b + a = c$

Thus the expression$8 + 7 = 15$, applying the commutative property, can be written as:

$7 + 8 = 15$

Answer:

Option c
