Look for keywords there. 

A number simply means x. 
Difference means subtract. 

And I'm not just going to give you the answer.

would it be 4? :/

cgreenwade2000 · Answer

the DIFFERENCE between a number (4) squared  and  the number (4)

We would write it as 

4^2- 4 

Which you can solve. You just need to read and Identify mathematical operations while reading.

Note that 4^2 does not  equal 8 . 4^2 means 4 times 4.
