Answer:

8 + 3 - 8 / 2  =  8 + 3 - 4
        -----

The single / has higher priority than the + and the -, so it is done first. Now there are two operators of equal priority, so they are done left to right:

8 + 3 - 4  =  11 + 4  =  15

Negative Numbers (again)

Priority of Arithmetic Operators
operator	meaning	priority
^	power	1
-	negation	2
*	multiply	3
/	divide	3
+	addition	4
-	subtraction	4

Examine the operator priority chart again. Notice that "-" is in the chart in two places. As you saw in chapter one, this is because "-" is used in two different ways:

The first meaning is "negative number". This use has high priority.
The second meaning is "subtraction". This use has low priority.

Since "negation" has high priority, it will be done first:

10 + -8 / 2 = 10 + (-8)/2 = 10 + -4 = 6

QUESTION 10:

What is the result of the following?

-12 + 2 + 4
