# Positive and negative numbers

Diego is tall, but Alfredo is short. Rishi is experienced, but you're a "noob" programmer. Comparisons are unavoidable in life. And the same thing is true in programs. So we'll continue practicing comparisons and displaying stuff on the screen. This time let's compare the entered number with zero and manipulate it based on the result of the comparison.

Hello Everyone, To complete this task go to Level 3, Lesson 12 (Financial Expectations). Copy what you did there, and then from there simply create an if, else if, and else statement!

Instead of "If the entered number is zero, display zero." it should be "If the entered number is zero, display 0." I was thinking that for the value of 0 I need to output the String zero.

You have to add the import java.util.Scanner; at the beginning of the code.

Is it better to write A:
``int num = math(myScannerClass.nextInt());``
or B:
``````int num = myScannerClass.nextInt();
num = math(num);``````
why?

If your code works in IntelliJ or another IDE but you get error messages when validating remove (or comment out) the prompt for user input!
