Evin evaluated the product of 5 x 12 as 60 by finding 5 x 10 and adding it to 5 x 2. this is an example of what property?

5 * 12 = 60
 For this case we have:
 5 * (10 + 2)
 = 5 * 10 + 5 * 2
 = 50 + 10
 = 60
 It is an example of the commutative property of multiplication.
 We note that this is equivalent to:
 5 * (2 + 10)
 = 5 * 2 + 5 * 10
 = 10 + 50
 = 60
 
 Commutative property.
