Question

which equation shows the commutative property of addition?
$4 + 3 = 3 + 4$
$4 + 0 = 4$
$(2 + 7) + 12 = 2 + (7 + 12)$
$1(3) = 3$

Explanation:

The commutative property of addition states that for any two numbers $a$ and $b$, $a + b = b + a$, meaning the order of addends does not change the sum.

• $4+3=3+4$ swaps the order of 4 and 3 while keeping the sum equal, fitting the property.
• $4+0=4$ demonstrates the identity property of addition.
• $(2+7)+12=2+(7+12)$ demonstrates the associative property of addition.
• $1(3)=3$ demonstrates the identity property of multiplication.

Answer:

$4+3=3+4$
