Which expression is an example of the commutative of addition A 4 * 6 * 5 = 4 * 5 * 6 B (4 * 5)* 6 = 4 * (5* 6) C 6 + 4 + 5 = 4 + 6 + 5 D 5(4 + 6) equal 50

Answer 1

The commutative property of addition states that the order of the addends does not change the sum. Therefore, if you have two numbers $a$ and $b$, the commutative property can be written as:

$$a+b=b+a$$

Looking at the options you provided:

A) $4\ast 6\ast 5=4\ast 5\ast 6$ — This demonstrates the commutative property of multiplication, not addition.

B) $(4\ast 5)\ast 6=4\ast (5\ast 6)$ — This demonstrates the associative property of multiplication, not the commutative property.

C) $6+4+5=4+6+5$ — This demonstrates the commutative property of addition, as it shows that changing the order of the first two addends (6 and 4) does not affect the sum.

D) $5(4+6)=50$ — This is an expression involving multiplication and addition but does not demonstrate the commutative property.

Therefore, the correct answer is:

C) $6+4+5=4+6+5$
