Write the Ruby code to check if the variable "a" is greater than the variable "b".

Ruby Operators using the greater than sign

This is the answer I'm writing on the code but is not correct even though I'm checking the correct answer the treehouse workspace?

"a" > "b"

The answer is false but I'm not sure what is not accepting my code?

Any help will be greatly appreciated, thank you.

You don't need the quotes. This makes the comparison happen on the string literals "a" and "b"

a > b

I got confused here as well!

I was confused as well - we used the quotes in the example in the video!

It's so frustrating to not have a hint here... I got confused with this as well. Would be nice to have a "reveal answer" option to move forward.

Just curious, in a real code situation wouldn't we need the quotes because we did not define what variables a and b are equal to?

Well, operation under the assumption that variables a and b exist wrapping them in quotes would never actually compare the values in the variables.

And comparing "a" > "b" is akin to writing the bool false. So I can't think off the top of my head where that would necessarily be useful.

ok, I figured it out. It was worth pursuing. You have to have a space before and after the operator.

I tried these on the challenge and got:

a>b fails a > b works.

There's no reason for the quotes in the question. It should read: "Write the Ruby code to check if the variable a is greater than the variable b." "a" implies that it's a string.

I also go confused....even rewatched the examples over and over again...the answer needs to be fixed to match the video.
