Question

Evin evaluated the product of 5x12 as 60 by finding 5x10 and adding it to 5x2. This is an example of what property?

Answer 1

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
Answer:
Commutative property.
