As I understand we neet to find rectangle
[ 9,2] -> 11
[-4,1] -> -3 = 15
[-1,8] -> 7

Task just poorly described.

I'm not sure if this was an exercise in coding, or an exercise in reading. I skipped to the bottom, see the patterns, and thankfully I was able to guess the solution.

Simplified description: If b is true, then return the string "true". If b is false, then return the string "false".

I don't think without "return" you can send any output with this method.

If we're going to engage in pedantry, the correct use would be "Hello, Name. How are you?" :)

NOTE: The correct use of comma in English is "Hello Name, how are you?".

When looking at the bottle from the bottom, it is a circle. In the circle you see a square with all corners touching. Looking from the bottle side, you see a rectangular cube (cubizoid). It fills the body of the bottle, but cannot extend into the rimLength.

You're right.
