Why is the order of operations important?

The order of operations gives us instructions on how to simplify expressions that contain more than one operation.

Let's look at an example.

8 + 2 · 3

The first thing you need to know about the order of operations is that multiplication and division always come before addition and subtraction.

So in this problem, we're going to multiply before we add.

Since 2 · 3 is 6, our next step will read 8 + 6 and 8 + 6 simplifies to 14.

I have also shown this problem in the image attached.

is there a question here?

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
