Using the sqrt method in the Math module, assign the value of the square root of 9 to the variable @sqrt.

This should be very simple!

Math::E = @e Math::PI = @PI

I set these variables to these values and the code is accepted, but when I input

Math.sqrt(9) = @sqrt

it says Task 1 is no longer passing. I feel like this should be so easy, so I'm not sure what to do now.

Thanks!

math.rb 
@pi = nil
@e  = nil
@sqrt = nil
Math::E = @e
Math::PI = @PI
Math.sqrt(9) = @sqrt

I would flip your variable assignments so they look like this

@e = Math::E 
@PI = Math::PI
@sqrt = Math.sqrt(9)

@sqrt = Math.sqrt(9)
Math.sqrt(9) = @sqrt

I have @sqrt = Math.sqrt(9) exactly and will not pass. Just a buggy system!

Has anyone passed this Task yet? I have tried everything and either task one is no longer passing or the @sqrt variable did not have the correct value.

This ends up working:

@sqrt = Math.sqrt(9)

That's funny ! I have the same problem now and I don't know to how figure out this ,,,

@pi = nil
@e  = nil
@sqrt = nil
module Math
  Math::E = @e
  Math::PI = @PI
  Math.sqrt(9) = @sqrt
end
