Answer 1

Hector need to find the sum of 50+83+50 b using mental math.

Hector simplify the expression 50+50+83 to find the required sum.

We can see that he has changed the order of addition.

We know that when we change the order of the addition then it doesn't affect the result. This law is called commutative property of addition.

This law states that for any real number x and y, we have

$x+y = y+x$

Therefore, Hector used commutative property .

The required sum is

$50+50+83\\ =100+83\\ =83$

Answer 2
