Identify the property demonstrated in the following equation: 60 times one equals 60. Is it a) the distributive property, b) the associative property of multiplication, c) the identity property of multiplication, or d) the commutative property of multiplication.
60 times one equals 60. We’re looking for a property that says the value times one equals itself. Immediately, we can rule out the distributive property, because to use the distributive property, you need to have parentheses or brackets.
The same thing is true for the associative property. The associative property is about grouping. And it requires brackets or parentheses. Choice c, the identity property of multiplication, is what we’re looking for.
The identity property of multiplication says that if you multiply anything by one, the result will be what you started with.
