Which property is illustrated by 45 + 19 = 19 + 45?

A. Commutative property of addition
B. Identity property of Addition
C. Associative property of addition
D. zero property of addition

Answer = A.

A. Commutative property of addition

The property illustrated by 45 + 19 = 19 + 45 is the commutative property of addition.

To understand why, let's first explain what the commutative property of addition is. The commutative property states that when adding two numbers, the order in which the numbers are added does not affect the result. In other words, you can change the order of the numbers being added, and the sum will remain the same.

Now, let's apply this property to the given equation: 45 + 19 = 19 + 45.

To solve this equation, you simply add the numbers on both sides. When you do this, you'll find that the sum of 45 and 19 is the same as the sum of 19 and 45. In other words, no matter the order of the numbers, the result remains the same: 64.

Therefore, the equation 45 + 19 = 19 + 45 demonstrates the commutative property of addition.

So, the correct answer is A. Commutative property of addition.
