You can put this solution on YOUR website! The general rule in "line" statements is that you work your way from left to right doing problems
in the following order:
.
First, do anything in parentheses (from left end to right end). Then return to the left end.
.
Second, work your way from left to right taking care of the exponents.
.
Third, work your way from left to right doing the multiplications and divisions as you encounter
them.
.
Fourth, work your way from left to right doing the additions and subtractions as you encounter
them.
.
The problem you were given is:
.
(6)(–5) + 2
.
You have parentheses, but there are no algebraic steps inside them. So you can skip Step 1.
.
There are no exponents in this problem, so you can skip Step 2.
.
For Step 3, when you go from left to right you encounter the multiplication of 6 times -5,
so you do it ... getting -30 ... and the problem then is reduced to:
.
-30 + 2
.
There are no more multiplications, so you return to the left side and for Step 4 you do
the additions and subtractions as you encounter them. In this case you do minus 30 plus 2
and get -28 as the answer.
.
So the answer to your problem is -28.
.
Remember the four steps above. They will be useful to you as the problems you are given
become more complicated.
.
Hope this helps you to see how you can do this problem.
