Answer 1

Saw this same question the other day.

Is there a reason why you are using square brackets and round brackets?

Is it simply
(428)(-23)+(-428)(-223) ?

If so, I am sure you have a calculator.
remember for the order of operation, the multiplication has to be done before the addion.

Answer 2

85600

Answer 3

It is simple.
The property used is Distributive property.

=85600
