mart [117]

Answer:

It makes the calculation easy and quick.

Step-by-step explanation:

  • <em>Commutative Property of multiplication</em>
  • <em>The product of two or more real numbers is not affected by the order in which they are being multiplied. In other words, real numbers can be multiplied in any order because the product remains the same. </em>

<u>When you multiply as it is given:</u>

  • 5×87×2=870
  • Step 1)  5×87 = 435
  • Step 2) 435×2 = 870

<u>Using the commutative property makes it much easier:</u>

  • 5×2×87 = 870
  • Step 1) 5×2 = 10
  • Step 2) 10* 87 = 870
