The commutativity property is used to get
-12×13×1/3 = -12×1/3×13
What is Commutative property?
According to mathematics, an arithmetic operation is commutative if switching the operands' positions has no effect on the computation's outcome.
When two numbers A and B are provided, the commutative property of the numbers formula is as follows:
A+B=B+A
A×B=B×A
A-B≠B-A
A÷B≠B÷A
According to the commutative property formula, the outcome is unaffected by the sequence in which two integers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, thus it cannot be altered.
How to solve?
The commutativity property is used to get
-12×13×1/3 = -12×1/3×13
such that the evaluation becomes easier, which is to get 12×1/3=4.
The commutativity property is used as follows:
-12×(13×1/3)=-12×(1/3×13)
