Logical Operators

[Everyman]

How would I write an expression that evaluates to true if x is non-negative and y is negative when they have already been declared and assigned values?

How do you test whether a value is negative or not?

I have been working with Equality and Rational Operators for the past few days, and this is my first time being exposed to this type of material. I have no idea how to test whether the value is negative or not, and the I have tried this:

"!-x"
"!-y"

Hint: When is a number considered negative?

When it is below zero, right?

Seems reasonable to me. Now do you see any comparative operators that test whether a value is less than another value?

These?:

"< less than"
"<= less than or equal to"

"< less than"

What happened when you tried them?

Good things. Good things happened, sir. Thank you for all of your help.

P.S.: This is the code that I used (x>=0 && y<0)

Awesome. Glad you got it sorted out.
