The property used to rewrite this expression is the___________.

When the expression is evaluated, the solution is____________.

Answer 1

When −46+87+46 is rewritten as −46+46+87, it shows that only change in positions of 87 and 46.

Change in order of sum of numbers doesn't change the result.

And when only order changes of added numbers, it will be a Commutative Property of Addition.

This propery could be shown by a simple expression

a+b = b+a.

So, first answer will be "The property used to rewrite this expression is the Commutative Property of Addition.

Now, let us evalute the expression by applying order or operations.

According to order of operations, we would could go from left to right.

−46+46+87.

So, first we add -46+46 = 0 ( by Additive inverse property )

0+87 = 87 ( by Identity Property of Additon) .

Therefore, answer for second part is ..

When the expression is evaluated, the solution is 87.
