Associative Property of Multiplication
Associative property of multiplication:
a×(b×c)=(a×b)×c
As with commutative property order is not important.
Indeed, you can make sure on a couple of examples, that it is correct.
Example.
From one side, we have that 3⋅(4⋅5)=3⋅20=60.
From another side, we have that (3⋅4)⋅5=12⋅5=60.
Warning. This doesn't work with division.
However, associative property of multiplication works for negative numbers (in fact, for real numbers) as well.
Example 2. 5×(3×(−4))=(5×3)×(−4)=−60.
Example 3. (−5.89)×(2.51×(−3.4))=((−5.89)×2.51)×(−3.4)=50.26526.
Example 4. (85×3)×21=85×(3×21)=1615.
