They want you to come to them for help.

Calculate the result of the expression, optionally assign the result to a variable, 
then print out the value of the result along with the indicated label.

You show the first two of those three steps.

Fix your indentation.

That variable name is not compliant with the Java naming conventions, nor with the instructions 
for your problem.

Try "problem1" as a variable name, and similarly for the rest.

These variables don't really need to be 'final'.

Now print out the values of those variables, along with the labels the instructions requested.

How wrong? Show us what you expected and what you got. 

Questions end in a single question mark, not two exclamation points.

Should be in a separate post, then.

How about you do the first problem first before you try to do another? Hm?

Really, doesn't your school have resources to which you can go for help?
